ADDITIONAL INFORMATION
Comment 1 nyanpasu64 2025-05-03 08:54:43 UTC
Problem seems specific to my dual-GPU configuration (main display on primary RX 570 over DVI, second display on integrated graphics over VGA). Corruption did not appear with iGPU disabled, or iGPU set to primary and monitor hooked up to iGPU (dGPU present but not in use). In my dual-GPU configuration, the corruption appears if the window is on either monitor.
