I tried creating a custom resolution @ 70 Hz and the artifacts went away completely without ha= ving to change the performance profile setting. The window stutter seems to be something else. I tried the PageFlip setting= to false as mentioned in another thread but that did not fix it for me. At 70 = Hz there's less stutter too though, not as noticeable as it is at 75.=20 It might be something to do with the monitor. I read in a review that the 38UC99 frameskips even in Windows when FreeSync is OFF. So could the issue = be that Linuux doesn't have full FreeSync support yet? I tested in Windows with FreeSync off, and it does stutter in a similar wa= y. Although, the cursor also stutters. The cursor doesn't stutter at all in Li= nux, as long as FreeSync is ON, so it does seem to be doing something. I'm not s= ure how to really debug this further though. --=20 You are receiving this mail because: You are the assignee for the bug.= --15283315661.f6B6B.17863 Date: Thu, 7 Jun 2018 00:32:46 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8" Content-Transfer-Encoding: quoted-printable X-Bugzilla-URL: http://bugs.freedesktop.org/ Auto-Submitted: auto-generated
