Description tadaddd111111 2020-08-22 10:52:59 UTC 
SDL is blocking window manager compositor. This can be fixed by turning off "Allow applications to block compositor" in systemsettings, howewer it's annoying, and it will not block also apps, where it is needed. There should be some function, such as SDL_Allow_Compositor(bool Allowed), or flag in SDL_Init() to leave enabled, or disable compositor.

Is this with X11? Set this environment variable:

    export SDL_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR=0


Or if you want to force it in your app, do this before calling SDL_CreateWindow:

    SDL_SetHint(SDL_HINT_VIDEO_X11_NET_WM_BYPASS_COMPOSITOR, "0");
