I don't have any issues on opensuse tumbleweed, on kde plasma wayland 
with Qt 6.11. Since a couple of Qt versions all wayland issues I had are 
solved.

System info:

Versie 2.5.1
(zondag 12 april 2026)

Qt-versie (run-time): 6.11.0 op platform wayland
Qt-versie (compile-time): 6.11.0
OS-versie (run-time): openSUSE Tumbleweed
Python gedetecteerd: 3.13.13 (/usr/bin/python3)
Teken-strategie: gedeeltelijk tekenen op de backing-store.

As maintainer of lyx on opensuse, forcing xwayland for lyx would not 
make me happy. I would say some evidence is needed that this is a 
widespread issue and that is indeed connected to wayland.
