Android Studio Emulator Screen Flickers

I have a new laptop with configuration: -
List item
Windows 11 latest build
Ryzen 7 5800H
16GB DDR4 RAM
RTX 3060 Ti Mobile GPU
Latest Android Studio
Latest Android Emulator
I have tried reinstalling the android studio and its emulators but its the same issue. Is this related to the presence of AMD processor ?
I have some ongoing projects which are halted and would like the get this problem fix as soon as possiable.
I have to develop some flutter applications

I think you can resolve this problem changing the render options to ones that best suit your system, test diffent values to find out what is best for you.
To reach this screen click on the 3 dots at the side of your emulator and then: Settings -> Advanced
Edit: I have used an computer with a Risen 5700G and a RTX3050 with no flickers, so It's probably a configuration issue, also check if you have virtualization enabled on your bios, it'll depend on the manifacturer of your motherboard so I can't provide clear guide on how to enable it on your system, if needed.

try to delete the current Emulator from .android/avd and install another one such as pixel 4 or pixel 3

It also works if you put the emulator in floating mode. At least it helped for me, and many others with similar problem. On he photos I only see that you have unpinned it, but not set it to "float".
Go to settings, view mode and then float:
I hope it helps, cheers!

Android emulator appearing as a small box in the top left corner of the window

Android emulator Samsung Galaxy S7 Edge
Hello, i have used this fantastic website many times over the years to find answers others have already provided. This problem i have not been able to find an answer to anywhere. As the title describes, every time i create a new Android Virtual Device using Android Emulator 2.0 within Android Studio 2.3.3 it displays the screen in the top left corner of the window. I have no idea why this is happening, i have tried uninstalling and re-installing HAXM. I have tried creating multiple different devices with different specifications and i always get the same problem. Does anyone know how i can get the screen into the correct position and the correct size? I'm operating on Windows 10 Cheers,
James

Solved, The external graphics(NVIDIA GTX1050) card in my device was interfering with Android Virtual Device.
Fix - When creating a new Android Virtual Device in the Verify Configuration window set Emulated Performance - Graphics: to Software - GLES 2.0

Can't change emulated performance of AVD in Android Studio

I can't change the graphics to software as I'm sure this is the fix for my AVD not launching.
The option is greyed out (see screenshot). Has anyone has experience with this? I couldn't find anyone who had the same issue.
I'm running the latest version of Android Studio on Ubuntu 17.04.

Actually, this problem seems to be limited to devices with Play Store available, so Nexus 5X and Nexus 5 images will be forced to use Automatic Graphics, but all other devices allow you to choose either Automatic, Hardware or Software graphics.
edit: I've just tested this today and it seems to no longer be the case. At least on MacOS with Android Studio 3.3.2, I can now make a Nexus 5X image with Play Store and Hardware Graphics. I'll do more testing at home later, on Windows and Linux to see if it's related to OS or graphics drivers.

I also think it's related to whether the Playstore is contained or not, but I cannot explain why.
Dielson Sales already gave the answer which worked for me - unfortunately only in a comment to this answer. I just thought it's worth to make a "real" answer out of it:
Edit the config.ini file of the AVD. Under Linux it's located under /home/<user>/.android/avd/<AVD-name>/config.ini
(in my case <AVD-name> is Nexus_5X_API_29.avd).
In a text editor change the lines
hw.gpu.enabled=no
hw.gpu.mode=auto
either to
hw.gpu.enabled=no
hw.gpu.mode=off
or to
hw.gpu.enabled=yes
hw.gpu.mode=host
This setting remains even if opened in the Android Virtual Device Manager of Android Studio. It's just not editable there.
I also tried this, which I found in another AVD:
hw.gpu.enabled=yes
hw.gpu.mode=software
But this is then changed to "no" / "off" by the Android Virtual Device Manager.
I didn't look any further so far. hw.gpu.mode=off worked for me. Otherwise my whole Kubuntu hangs (using the Nouveau driver, not the NVidia driver)

Seems like the problem was with the choosen VM. If I choose a Nexus 4, it runs just fine.

I am little late on this thread but following are my findings and solution. I am using Ubunut 18.04 and faced the same issue. The solution is to edit AVD and under Emulated Performance, change the grpahics to Software. The problem was that this option was disabled for me. I was unable to change graphics drop down.
I did some more research and found that while creating AVD if you choose default/existing device definition on first screen, you will not be able to edit graphics drop down.
The solution is to create a "New Hardward Profile" while creating AVD and use your new profile. Now, you will be able to edit "Grahics" drop down.
Hope this helps....

It seems all emulators with Play Store cannot emulated performance. I am using AS 4.0

Open Android Virtual Device Manager Android Studio, change VMHeap to 512, RAM to 4096 MB. Then restart Android Studio.

I think It's just a bug!
Solved the issue by selecting any virtual device had the option enabled and after finishing the installation I just clicked on edit and reselected the device I wanted and the option was still enabled.
Click on edit button from here.
Then change the device to the one you want.

For those who are still searching for solutions on how to make it work with an image containing google play store: install / update your GPU drivers solves the problem. On my Ubuntu 20 this was the issue.

I'm working on mac os - after i upgrade my os my emulator stoped working and one of the solution was to change the graphic settings from hardware to software - since i couldn't - came here ---> turns out Android Emulator HAXM on macOS High Sierra is left out from security reasons

Fonts are blurry / big in Android Studio

is there any way I can change the resolution of Android Studio? I looked in Settings->Appearance but it seems like there is no official way to change it. I have a 1920x1080 Display and the whole window and text looks a little bit blurry. I am running a Windows machine on Windows 8.1.
Thanks!

You need to set a compatibility option "Disable display scaling on high DPI settings" for the application.
Right-click the taskbar button, then right-click the app name, select Properties, Compatibility. Set the option, save changes, restart Studio.
Those instructions are for a Win7 machine, but Win8.1 should behave the same.
To explain what is happening: apparently, the Studio is not "high DPI aware", i.e. does not declare "I know how to handle myself on a high-DPI screen", and Windows tries to scale the window so that its elements do not get too tiny.
You can override this on an app-by-app basis, but be prepared for possible glitches / tiny UI elements.

Right click on your android studio icon. Go to : Properties -> Compatibility.
Check the "Override high DPI scaling behaviour" option also select "Application" for "Scaling performed by" from the drop down menu.
Press apply and restart your android studio.

I am using Windows 10 and I am facing the same problem.
I know, I know ... why not to switch to Linux? So this won't be a problem..., but the fact is that my company gave me this notebook with Windows :/ and I've been too lazy to format and reinstall OS.
In my case the problem occurs because sometimes I use an external monitor, and sometimes I don't.
When I use the external monitor, the sources are very blurry.
In my case, what worked was
Right click on Studio icon \ Right click on "Android studio" item menu \ Properties
Compatibility \ Change Settings for all users
And now, when using external monitor
Check "Run in Compatibility with... Windows 8", and click on Change high DPI settings
Check "Override High DPI with... system"
Hope it helps.

Modify the font size in the "File > Settings..." screen on Windows

Try changing your PC's theme to Windows 7 Basic. Control Panel>Change Theme. Set it to Windows 7 Basic (should be under the "Basic and High Contrast Themes" header) and see if that fixes it. You may need to restart Android Studio to have the changes take affect. I had this issue too and it bugged the crap out of me and somehow I figured it out. Hope this helps!

Preview Nexus 10 layout on Eclipse with ADT R21

For some reason, after updating the ADT to R21, I cannot preview my layout on any type of size like I could before :
So, I declared a new Android Virtual Device by using the AVD manager and there, I can't found anything that could look like a Nexus 10 resolution :
Is anyone having the same trouble ? How can I preview a Nexus 10 layout with the cool "Preview All screens" feature ?
Thanks in advance.

You need to create a new 'Device Definition' for the Nexus 10 and populate it with the information regarding resolution, ram etc for that device. You can find the 'Device Definition' tab in the Android Virtual Device Manager. Once you create the new device definition, it will appear as an option in the 'Create New Android Device (AVD)' dialog box.
Good luck!
Note: I am running Mac OS X 10.8.2 and Eclipse ADT v21
