It’s a reasonable thing to test for, and fairly easy to reproduce. It’s something to rule-in/out for sure.
This is understood, but to put it into perspective, it’s the difference between being able to do my work for my clients, or not. Changing that setting fixed an issue with negligable side-effects for months, permitting me to work unhindered by KDE GPU memory issues, at least until this update.
Unfortunately, it’s a fix that’ll need to be re-assessed.
