Created attachment 163163 [details] screenshot STEPS TO REPRODUCE 1. use Wayland 2. apply an icc profile in Display Configuration KCM 3. apply 125% scale OBSERVED RESULT Plasma panel becomes black when I interact with it. Any popup/menu from Plasma panel is black on opening and gets stuck on the screen. These Plasma bugs disappears if I remove the icc profile from Display Configuration KCM. Please see the attached screenshot - the incorrectly rendered parts are white instead of black. EXPECTED RESULT the described problems should not occur SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.27.80 KDE Frameworks Version: 5.245.0 Qt Version: 6.6.0 Graphics Platform: Wayland
Could you attach that ICC profile so I can test with it? I don't have one.

Can't reproduce. Do you have any non-default effects active?
Yes, Background Contrast and Blur. If any of them is disabled, the bug stops happening.
Cannot reproduce with those settings and that profile.
Now only Blur and default effects are enabled on my system and the bug happened again. :(
So now it's happening when not using an ICC profile, and not using a fractional scale factor?
I was also using the icc profile and fractional display scale when the event mentioned in comment 6 occurred. Therefore, I do not need to enable both contrast and blur effects to trigger the bug. I can easily reproduce with both effects enabled, but at the moment only one of them (blur) is enabled and so far the bug has only occurred once.
It's not a bug related to fractional display scale. Now I'm using the icc profile and display scale 100% and the bug has happened again.

Is this the issue you speak of? If so, then here is a recording of it happening to me while I have an icc profile set. It doesn't happen all the time, but it only happens when an icc profile is enabled: https://streamable.com/budmuk. Look at the task bar and the glitchiness in Kicker.
This bug persists on Plasma beta 2. The problem occurs after using the computer for a few hours. Then I restart the plasmashell process and use the computer for a few more hours until the problem occurs again.
I've been running my desktop and laptop with an ICC profile for the past week and have yet to see this happen. What GPU are you using?
Processors: 4 × Intel® Core™ i5-4670K CPU @ 3.40GHz Graphics Processor: Mesa Intel® HD Graphics 4600
I'm unable to reproduce the bug either
The same rendering bug have just happened on my neon unstable installed on another machine. I do not use any icc color profile on this machine, but I have night color activated on it (and on the another machine initially affected). Operating System: KDE neon Unstable Edition KDE Plasma Version: 6.0.80 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 Kernel Version: 6.7.5-060705-generic (64-bit) Graphics Platform: Wayland Processors: 4 × Intel® Core™ i3-3110M CPU @ 2.40GHz Memory: 15,5 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 4000

I have the same issue, but I don't have scaling. It doesn't matter if I have blur enabled or disabled. It looks like it makes background less transparent. Without ICC profile: https://imgur.com/a/71o0Zxq With ICC profile: https://imgur.com/a/snoncJN

It looks like it makes background less transparent. > Without ICC profile: https://imgur.com/a/71o0Zxq > With ICC profile: https://imgur.com/a/snoncJN I am seeing this issue in wayland as well. A good way to reproduce is to set the color profile to 'none'. In the konsole profile settings set background color transparency to something like 20%. Observe that the window is not very transparent and the text is easily legible. Then change the color profile to an ICC profile and click apply. Observe that the konsole window immediately becomes much more transparent and the font is harder to see. I am running plasma 6.1.1 with nvidia driver 555.52.04. I am not positive that this problem and the original issue are the same. This might require another ticket.
That's a different thing, see bug 476868

I believe the 3rd party windows shader effects Burn My Windows, may be suffering from this issue too https://github.com/Schneegans/Burn-My-Windows/issues/432
