Found the fix went into other settings, then alternative emulator, and selected QuickNES...is what worked for me

It's not just one emulator. And none of my examples were nes

Found the root cause, it was the video display d3d11. Using Vulkan completely cleared this up

I never tried Retroarch by itself without installing via EmuDeck on Windows but I also had run into this issue.

I also eventually figured out by changing the drivers to anything but Direct X, this issue went away. But that had other undesirable issues such as Borderless Fullscreen Window didn't work properly so clicking off the screen would cause a display switch which blacked out the app for a few seconds before it is restored.

The root problem that I was able to find was that On Screen Notifications in Graphical Mode didn't display properly and the flashing white text is Retroarch not being able to render those notifications at all.

By turning off Graphical Notifications, the white flashing went away and I was able to set Retroarch back to Direct X. The notifications now appear, but it's just simple yellow text. Would be great to get the Graphical Notifications working though.

I had this issue as well using ROG Ally with RetroArch 1.17 using the official ROG Ally Gaming Charging Dock - when using in handheld mode, I don't have these issues.

I was also experiencing some screen tearing and audio issues with PlayStation cores while docked. None with Duckstation standalone

I figured this out!!! Was driving me crazy... Disable bezels... I did it through the Emudeck front-end... Solved all of my issues of random white symbols and letters flickering during all games...
