I can confirm this on Fedora rawhide RC1 Cannot reproduce on X11, AMD (In reply to Fushan Wen from comment #2) > Cannot reproduce on X11, AMD Then maybe it is a wayland only issue. Fedora has dropped the x11 session so I can't test it. (In reply to Fushan Wen from comment #2) > Cannot reproduce on X11, AMD Then maybe it is a wayland only issue. Fedora has dropped the x11 session so I can't test it. Reproducable in x11 on intel graphics I can reproduce some weirdness too; in my case the screen goes very dark instead of bright. Not sure what's causing it though On amd this does not uccur (neither in wayland nor in x11). But i can reproduce it on the nouveau driver (i cannot test on nvidia prioprietary driver because it blackscreen at the moment) A possibly relevant merge request was started @ https://invent.kde.org/plasma/kwin/-/merge_requests/4994 Git commit 4cc94e9462cdac8a60db26e34573dcd07231cd9f by Vlad Zahorodnii.

Created attachment 164869 [details] Image of screen after setting change SUMMARY The screen after changing that setting is almost completly white but it is only a graphical problem, as in the system still work as normal. It became whiter as time goes on so, so maybe it is some kind of multiplicative effect where the effect is applied on the same image multiple times. STEPS TO REPRODUCE 1. Go to Window Managment -> Desktop Effects 2. Enable Colorblindness Correction 3. Click apply * This apply to both 5.92.0 and today's master branch. OBSERVED RESULT The screen is almost completly white. When enabling it become more and more white. It is still possible to disable it by entering overview, understanding where to click (or to tab to) and disable colorblindess and click apply again. EXPECTED RESULT The screen should have slightly different colors. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.92.0 KDE Frameworks Version: 5.248.0 Qt Version: 6.7.0 Kernel Version: 6.7.0-arch2-1 (64-bit) Graphics Platform: Wayland Graphics Processor: Intel ADDITIONAL INFORMATION I think it is a major bug because it could make it almost unusable and it is diffult to disable it.
