It did fix it! Thank God! I was to lazy to downgrade and was just waiting for a fix

With VRR on, many games started flickering. Some were unplayable, like every other frame was black.

It's fixed on the latest version. I already have it on arch

Hopefully GloriousEggroll will update wine get soon!!!

Fixes client and game opening in the background on gnome and not able to be maximized/visible

Can confirm. Luckily league can be played on the main wine next patch
