Windows - White flashing text on various games

Description

Garbled, consistant white text flashes on screen at game launch through retroarch cores.

Expected behavior

When you launch the games, it's expected for the games to load properly without extraneous graphics or text

Actual behavior

Game launches and flashing, flickering text displays over screen, including bezels.

Steps to reproduce the bug

1. Launch game through emulation station DE (installed through emudeck) interface
2. Game Launches
3. Within a few seconds, flashing white text will appear on screen

This is a UM773 with a 7735HS, integrated 680M Radeon GPU

Start by reproducing the flashing text through the EmulationStation DE and EmuDeck launch path on Windows 11 with the UM773 hardware, then inspect the attached RetroArch logs and video evidence. Compare affected cores and rendering behavior; done means games launch without flashing text or extraneous graphics, including over bezels.
