I dont use Wayland at all, so just using information provided at #13305.
If it was fixed by new Qt version, that would be great. But I see Radeon
on the reporter's side and this smells like the real culprit - some drivers
for gpu accelaration might break stuff...

I do not have any opinion and can revert if you think the default
on Wayland works fine.

Any other Waylanders around to report their experience on xcb vs non-xcb?
