Comment 3 Nate Graham 2024-10-10 20:08:43 UTC 
Looks similar to Bug 488713, but that was in KWin and got fixed for the 6.2.0 release already.

Is this a regression in 6.2.0? Was it not happening in 6.1 at all?
Comment 4 Nicolas Fella 2024-10-10 20:39:43 UTC 
The backtrace looks entirely different though

I have had this issue since 6.1 and I look forward to getting it fixed in 6.2. But in fact, this problem seems to have become even more serious because my monitor brightness also had issues in 6.2.
Comment 6 Nate Graham 2025-04-08 19:52:40 UTC 
jcfun, is this still happening in Plasma 6.3.0 or later?

Also, how many monitors do you have? When you turn off one, is it the only monitor, or are there others still turned on and active?
