--- Comment #80 from tempel.julian@gmail.com --- It seems like the issue is actually not 100% resolved (linux 5.0-rc1). The moving of windows is free of stutter now, but moving of windows can still negatively affect performance of other windows as long as fullscreen vsync is enabled (not necessarily via compositor, can also be done via TearFree without a compositor). Again, this is best seen on https://www.vsynctester.com/ . This seems to happen mostly when mouse clicks occur, but sometimes also apart from this. It can also happen when just moving the mouse cursor repeatedly on top of shell elements which trigger pop ups, like the system tray of KDE Plasma. As expected, setting amdgpu.dc=0 completely "fixes" the issue.
