This often occurs on my machine when using a Wacom tablet, but not when using a mouse. I haven't been able to figure out how to reproduce it consistently.

Comment 2 H.-P. Sorge 2025-06-23 10:28:31 UTC 
I "played" around with  System Settings/Window Management  and changed  whatever parameter is mouse related.
Now LMC is working again. 

There are several changes in .config/kwinrc.
The most noticeable is an additional entry compared with kwinrc from 10 days ago:
[Xwayland]
XwaylandEavesdrops=All
XwaylandEavesdropsMouse=true
 
Just a mention. Not sure if it's related.
