Describe the bug
If Freesync Premium is enabled in monitor settings, turning off monitor and then turning it on cause monitor to continuously turn on/turn off. It's not losing any signal.
Always happens when monitor is turn off because of power management and if you turn it off by hand.

More Info
- Doesn't happen on X11
- It can be stopped by switching to tty via ctrl + alt + f3, than back.
Expected that monitor is always turn on without any issues (like it did on X11)
Can't use X11 because on Fedora 42 it's borked.
conceal_vrr_caps param helps to disable VRR without tweaking monitor settings, but looks this looks like bug anyway
Thanks for the bug report. I see the monitor in use is a GBT GS27U. I'll try seeing if we can get an internal reproduction to debug this.
