far2l WXGUI version

KDE on Wayland.
Using 115% scaling in display settings on Nvidia GPU (prop) seems to cause jumping in non-QT applications, wx-GTK in this case (see attached video).
This behavior stops when setting scaling to 100%.
150% scaling doesn't seem to cause the same behavior, at least on AMD GPU.

Just to make sure, I disabled _all_ animations, desktop effects, etc.
