My GPU is a Sapphire Nitro+ Vega 64. I am using Gentoo with Mesa git and KDE Plasma 5. My main monitor is connected over DP and runs at 2560x1440 at 144hz. My second monitor is connected over HDMI and runs at 1920x1080 at 60hz. I tried disabling the second monitor in KDE, but the issue still occurs. It also occurs in fullscreen applications. I will also attach dmesg. I can test any patches or answer any questions.
