TV screen blinking when set to 4k@120Hz, but only in steam menu
Hi,
I have a problem that didn't occur a couple days ago, so my screen is blinking when I set 3840x2160 120Hz resolution. I would assume, that this is HDMI connection problem, but it is blinking only in Game Mode, when the game is not started yet. When I start the game, everything returns to normal. Also, when I enter desktop mode everything is working as well. And I have dual boot with Windows, and on the same setup it works at 4k@120Hz. It is strange behavior that it is only blinking in game mode when the game is not started yet. When I start the game, 4k@120Hz with VRR and HDR work just fine. Everything is updated to current version (Steam OS, bazzite and Flatpack apps).
Specs:
CPU: AMD 7950X3D
TV: Samsung 75QN95A
GPU: AMD 7900XTX
OS: Bazzite (Fedora 41) with KDE

And I forgot to mention, 4k@100Hz also works fine, so when I'm in steam menu I can operate at 100Hz and then, when in game, I can change resolution to 4k@120Hz and there is no problem with blinking. But when I return to game mode it starts blinking again, because of 120Hz. So it is a bit of pain in the ass to change it frequently, especially when it was working couple days ago without any problem.
Problem started after updating one of the components, I guess. But I updated it simultaneously so I cannot point on what exactly broke my setup.
The newest version of Steam OS resolved this problem for me. I didn’t update anything related to bazzite so it was definetly Steam OS problem.
