Regressions on GNOME Wayland when updating Qt 6.2.0 to Qt 6.2.2.

I've updated our app (Telegram Desktop) to Qt 6.2.2 from Qt 6.2.0 and faced huge amount of reports from GNOME users on Wayland, including a lot of reports from LTS distro versions. All of them were caused turning off the XWayland usage by default on GNOME.

I'm not sure that this is acceptable, because those users get their experience broken in many ways just by updating Qt to a mostly-bugfix patch version.

Here are some reports, like scaling issues, flickering:
