The behavior of the bug really varies between apps and boots. Now, for example, YouTube fullscreens fine without any glitching of the video or artifacts on the other screen. However Minecraft fullscreened at launch, but with half of the other screen being black. When I tried unfocusing and focusing Minecraft, it would turn both screens black for a second before appearing only maximized and not fullscreened (like experienced before with other games). It won't fullscreen again unless i quit the game and relaunch it.

Other websites, like Netflix, will fullscreen for a second and de-fullscreen after that. Some games act weirdly in fullscreen mode (this might be related, as I've never had this issue before now: https://github.com/ValveSoftware/csgo-osx- linux/issues/2429). EDIT: This only happens when fractional scaling is enabled. My config; main 4K screen at 150% and secondary 1080p screen to the right at 100%. YouTube fullscreens fine on the sec. screen (1080 100%).
