This is because Tomas missed to inform us if he was using a wayland application
or an X application. However, even with an X application the font is rendered
on the client side - must likely by a toolkit. Thus we also need to know
whether this was a Gnome, Plasma, XFCE or whatever else application.

The issue should be investigated on a toolkit level - if anything is missing in
Xwayland that leads to this the graphics stack team can handle this.
There is no use to pick X as the default culprit.
