My gpu is AMD Radeon RX 6600, I have latest drivers including:
mesa 1:25.1.6-1
lib32-mesa-1:25.1.6-1
vulkan-radeon 1:25.1.6-1
lib32-vulkan-radeon 1:25.1.6-1
and latest linux and linux-firmware:
linux 6.15.8.arch1-1
linux-firmware 20250708-1
The problems:
1. When my monitor refresh rate is higher than 100Hz, monitor flickers when any action occurs, moving my cursor, opening/closing windows, etc.
Meanwhile the highest refresh rate is 180Hz, the temporary solution was to set
/sys/class/drm/card1/device/power_dpm_force_performance_level to high, however it causes my gpu to coil whine, the other "solution" was to power on my monitor just after hyprland launched with 180Hz, which is very inpractical, but it worked and it wouldn't cause coil whine
2.The second problem is that vrr does not work at all, when I turn vrr on in hyprland config, It is like I unplugged the HDMI cable, no output at all, I have no idea why it does not work
Important info:
It is not a hyprland issue and my cable (HDMI 2.1) is not faulty, 180Hz works fine on xorg or windows11
The problem occurs in:
hyprland
sway
kde plasma (wayland session)
If there is any information that could help in solving the problem, and I forget to post it here, please let me know
