I see something similar using an NVidia card.

Early in the log I see these errors

[AVHWDeviceContext @ 0x562dd8ad6cc0] libva: va_getDriverName() failed 
with unknown libva error,driver_name=(null)
[AVHWDeviceContext @ 0x562dd8ad6cc0] Failed to initialise VAAPI 
connection: -1 (unknown libva error).


Then later  same as Klaas

Attempted flush to non-raster surface QWidgetWindow(0x562dd85e7270, 
name="mainwindowWindow") of type QSurface::OpenGLSurface (consider using 
Qt::WA_PaintOnScreen to exclude from backingstore sync)
Attempted flush to non-raster surface QWidgetWindow(0x562dd85e7270, 
name="mainwindowWindow") of type QSurface::OpenGLSurface (consider using 
Qt::WA_PaintOnScreen to exclude from backingstore sync)
