--- Comment #80 from tempel.julian@gmail.com --- Oh my. I've tried the oldest Proton build offered by Steam, which is based on Wine 3.7, and indeed it doesn't show the issue (neither in Oblivion with wined3d OGL nor Hitman 2 DXVK Vulkan). I tried with the older Proton 3.16 version before, which unfortunately is the one that started showing the issue. I don't know why I didn't try 3.7 in the first place. I'm sorry for the time you have invested into this issue. :( Though it would appear to me that the old non-atomic DC is very resilient toward such issues. To be sure, I also tested with untouched Arch 5.2.13 kernel: Without that Wine commit, it is totally free of that stutter issue as well.

Pierre-Eric, I reverted that commit c6b6935bb433dbbd30f5ba122a7c45ad3a2d6eed, and indeed, it introduced this issue. Should I create a Wine bug ticket for this?

Closing now. Big thanks @ Michel and Nicholas for their great support. AMD's kernel and Linux windowing support is simply outstanding, a dam good reason to stay with team (former) red. :)
