Hello, I'm having an annoying X11 issue. The machine is latest Fedora 32 x64, AMD Ryzen 3 2200G with Radeon Vega Graphics, Gigabyte B450M DS3H, latest BIOS. xorg-x11-server-Xorg-1.20.9-1, xorg-x11-drv-amdgpu-19.1.0-3, Linux 5.8.16, openbox minimal desktop (no Wayland).
The user plays a 32-bit WINE game (a ~2005 DirectX full screen, details are of course available). Then switches with Alt-Tab back to X, nothing bad happens yet. Switches back to the game, all is good, and only then switching (for the second time now) with Alt-Tab to X desktop kills the graphics. A different computer (with an AMD BARTS chip and radeon driver, same software) doesn't have such a problem. The question is, how do I debug such things?
