https://bugs.freedesktop.org/show_bug.cgi?id=110199 --- Comment #9 from Eduardo Saporski --- Can confirm. My GPU is MSI RX580 Armor 8G OC and my monitor Asus VP247QG (FreeSync, 48Hz to 75Hz). I'm on Solus 4 using the open source drivers (POLARIS10 DRM 3.27.0 5.0.5-113.current LLVM 7.0.0, OpenGL version 4.5, Mesa 19.0.0) and the flickering is exactly like Maxim showed. The workaround is setting DPM to high: "echo 'high' > /sys/class/drm/card0/device/power_dpm_force_performance_level" -- You are receiving this mail because: You are the assignee for the bug.
