Laptop sleep may affect VRAM drawing

Lix 0.9.36 on Windows.

Flopsy played a multiplayer session with me. He is red. Whe he was platforming over the porcupine, he accidentally hit F1 on his Windows laptop, which sends the laptop to sleep mode. Flopsy immediately exited sleep mode, and saw the game again. All this this happened within 2 seconds.

For the rest of the game, Flopsy saw wrong graphics, but had correct physics, i.e., physics did not desync. In the wrong graphics, over the porcupine where the cursor is, there is a hole in the red bridge. This hole is exactly one platformer brick wide. In the correct physics, there is no hole here, the platform is continuous.

Graphics are in VRAM. It's possible that the VRAM write failed without feedback while the Windows laptop was sleeping, or while the laptop went to sleep mode.

Flopsy's laptop runs Windows 10 with Intel graphics.
