[MCPE-231673] Severe horizontal flickering lines appear only in fullscreen mode on Windows after recent GDK update (not visible in screen capture)

I’m getting large horizontal flickering lines in Minecraft Bedrock Edition whenever I use Fullscreen mode with Fancy Graphics. The issue appears everywhere, including the title screen and UI.

Notes:

Started after the recent GDK update
Flicker does not show up in OBS captures
Not a display issue - older Bedrock versions and other games work fine
The issue goes away when Fancy Graphics is turned off or when not using full screen

Repro:

Enable Fullscreen
Turn on Fancy Graphics
Flickering lines appear immediately

I’m having a similar issue! When I try to fullscreen, my screen either turns completely white with flashing black lines, both horizontal and vertical, or begins violently flashing between a white screen and the game screen. Fullscreen does occasionally work without these flashes, but the majority of the time it results in these glitches. Game audio continues as normal during these glitches.
