Android Studio – Android Studio Avd emulator shows a black flickering

I have an issue all of a sudden where I am getting a weird black flickering at the bottom of the screen (as shown in the video below). I had no problem earlier also this happened after I removed android emulator and rechecked it (Reinstalled it ) under the setting “Tools” ->” SDK Manager” -> “SDK Tools” tab.

Computer Specs –
I7 – 10750h,
Nvidia 1650 Ti – 4GB,
16 GB Ram,
1 TB SSD (443 GB free)

Also, I have noticed the screen goes most of the part blank when I am not touching the screen.

    I had the same problem recently after create a emulator with API level 33,
    Then I’ve tried to used API level 31 and emulator works normally.

    Same here. After one of the latest Emulator (in SDK tools) updates virtual device with API level 31 or above show same issues. Devices with API level 30 or below work fine.
    Tried to completely clean and re-install Studio and Video drivers. No effect.
    So since it started right after update i believe it’s Emulator component issue.

    It seems there is a problem with the x86_64 images. If Software GLESS is turned on then the flicker goes away but the graphics are little laggy.
    x86 images works well smooth but out-dated.

    I just installed Android Studio first time for a while and noticed the flickering problem right away. I have NVIDIA GPU which most likely contributes into this problem. In the AVD options inside the Android Studio device manager I tried switching the Graphics setting from automatic to "Software GLES 2.0" and it fixed the flickering. No way using software acceleration is optimal in any way but it could be a workaround until the root cause is fixed.

    EDIT: found the issue posted about this behavior confirming it is a GPU driver related issue https://issuetracker.google.com/issues/246917660

    I just switched to a Pixel 5 with API 33 and it seems to have resolved my flickering problem..

    I tried giving more memory (4096 RAM) to my emulator and the issue disappeared.

    I had a same issue in my new laptop. I have fixed it by changing one parameter in the emulator’s config file.

    • Go to C:UsersUSER_NAME.androidavdPixel_5_API_31.avd
    • Edit the config.ini file.
    • Find the "hw.gpu.mode = auto" and change it to the "hw.gpu.mode = guest" and save the changes.
    • Restart the emulator.
