There is no TearFree in modesetting driver yet. :-( https://bugs.freedesktop.org/show_bug.cgi?id=98876 Not sure whether anybody is/was working on this already. -- You are receiving this mail because: You are on the CC list for the bug.

Can you please help me a little further to reproduce your issue? Which desktop environment are you using? Certain compositors, such as the one in Xfce, are known to be unhelpful in the tearing department...

Argh, missed that it's Plasma. Thanks! -- You are receiving this mail because: You are on the CC list for the bug.

I'll try to set up a similar configuration here one of the coming days (i.e., next week...) and try to record some movie with an external cam if I can reproduce it. In any case I'll report back.

It is quite different from the old one though: Here I only have a FHD HDMI monitor. Th old setup had a same-sized monitor connected via DP on the dock. As the dock doesn't have HDMI it is now connected to the laptop directly. The tearing is still there, but has improved. The most anoying one had been in the browser window when scrolling. This is not really prominent anymore, but the diagonal line(s) can still be seen when slide-changing the desktop. Full Screen repaints: I am quite sure I had tried that in the old configuration, and it did not improve things. Also now, I don't see a real change in tearing whether it is on or off. I also tried changing the primary display now, but again no change. On the bad side, now I (sometimes) get strange color artifacts around windows when changing the focus (I use follow mouse, so just moving the cursor around across various windows is enough to trigger it). This happens on both monitors but not when only one is connected (I'm running modesetting as default, with only one monitor it is having no issues for me at all). Recording things with an external camera so far was not successful, that's why I tried to describe things.... Yes, as Stefan mentioned in Comment #1 adding the TearFree to the driver, like radeon and nvidia have, is what is likely the only cure for this. -- You are receiving this mail because: You are on the CC list for the bug.

I'm back to the other location since two weeks and wanted to come back on this myself. So the first report is that things seem to have improved, at least I did find the flickering (while still present) less disturbing now - it's basically only strong during the slide animation when switching virtual desktops. Not sure if there had been any changes in the code, or whether it's just me sensing it differently... About the tip itself: I tried it. The vsync was set to 'Automatic', so I switched to 'Never', but couldn't see any difference. Then I noticed that it seems to be a tip for the Intel driver, not for modesetting :o -- You are receiving this mail because: You are on the CC list for the bug.

Please give the tip on intel a try. And also the QT fix. -- You are receiving this mail because: You are on the CC list for the bug.

For the QT fix to apply you would need update the QT package with the fix. Where to find it? Honestly I don't know. I no longer find the bugreport for it. :-( -- You are receiving this mail because: You are on the CC list for the bug.
