Maybe there's some settings on the screen you can tweak? Hi! Thanks for the reply. It definitely seems related to that, since changing the refresh rate to 120Hz fixes the problem. What's stranger is that, when running the same setup on Windows (1440p resolution at 170Hz with HDR on) text looks fine. The only limit to the bandwidth seems to be either 8 bit when running above 120Hz, with 10 bit working below that. Why does KDE require 10 bit to display color correctly when Windows can do that with 8 bit? -- You are receiving this mail because: You are watching all bug changes.
