Symptoms

After the game's latest update a couple of days ago, whenever I try to put the game on Borderless Windowed mode, the screen flickers uncontrollably.

This behavior can be seen in the following video:

I have two monitors, and this behavior happens equally if both monitors are running and if only one monitor is running.

Reproduction

Sadly I have no idea how one could reproduce this bug. It may as well be a configuration issue on my end, any help is appreciated.

Strangely, I also have a laptop where I play SF6, It doesn't have a graphics card, but the processor is AMD too, and it still plays the game perfectly without flickering, even in borderless fullscreen. The distro, Kernel, Mesa Driver and Proton versions are the same, too.

Thank you very much in advance for any help.
