Since I had my new GPU (AMD RX9070XT), I had enabled the function AMD FreeSync for my monitor (MSI MAG27CQ), Unfortunately, this result with a serious backlight flickering very very annoying and eye burning… :-/
”The internet says”, this problem is “famous” with linux and wayland (true ?)
Question is simple, is there any workaround to fix it ?
Or should I need to switch back to X11 for this option ?
And on X11, how to enable this ? Because the function doesn’t appear on the display control pannel :-/
Just wanted to point out this section of the very same article on variable refresh rates, which recommends to use a Displayport connection. Your Monitor, at least from what I’ve found, doesn’t have HDMI 2.1, only an HDMI 2.0 port. VRR over HDMI would require HDMI 2.1.
In my case, my RX 6600 does have a HDMI 2.1 output with VRR support. But my Monitor only has HDMI 2.0 inputs. When I activate adaptive sync via the Display settings of KDE Plasma, my display won’t flicker, but would turn off when I maximize windows.
Therefore, as my monitor doesn’t have a DisplayPort input, only an USB-C port with an alternate DisplayPort 1.4 mode, I simply don’t bother with it and disabled adaptive sync.
