SUMMARY Blur effect when software brightness is used is incorrect. STEPS TO REPRODUCE 1. Turn on Blur effect. 2. Disable DDC/CI brightness. 3. Set brightness to very low. OBSERVED RESULT Plasma tooltips are brighter or white. EXPECTED RESULT Plasma tooltips looks as in 100% brightness, but dimmer. SOFTWARE/OS VERSIONS KDE Plasma Version: 6.5.0 KDE Frameworks Version: 6.19 Qt Version: 6.10.0 ADDITIONAL INFORMATION It's a regressions, on 6.4.5 it looks correctly. In HDR and 0% brightness tooltips are white and text is also white. On screenshots it looks correctly. If the blur is enabled and plasma is using basic renderloop, resizing plasma windows flickers to white with full brightness for a short time.
Same happening for me too.

Still happens in 6.5.3.
> It's a regressions, on 6.4.5 it looks correctly Did you use to disable the background contrast completely in 6.4?
Also, out of curiosity, are you in #kwin on matrix? If so, what's your username?

I don't have 6.4 anymore, but tested on 6.3.6: yeah it seems to be contrast issue - with contrast it's wrong on 6.3, without contrast it's correct (most likely I had contrast turned off in 6.4, too).
