Bug 81385

Are you using kwin or comptom?

If kwin, please check https://bugs.freedesktop.org/show_bug.cgi?id=80349 and https://bugs.kde.org/show_bug.cgi?id=336589

So I applied the fix, rebuilt kde workspace, installed, but it still happens.

Hmm, and I tried to checkout 251bcc32eed3 and it still happens. So it must be something else :/.

Is:

[     5.703] (II) intel(0): direct rendering: DRI2 DRI3 enabled
[     5.703] (II) intel(0): hardware support for Present enabled

new?

You can try: xorg.conf:

Section "Device"
  Identifier "Intel"
  Option "DRI" "2"
EndSection

According to attachment 102302 [details] from bug 80948, yes.

Tested, I think I haven't seen what I originally reported here yet.

But there is still a glitch: hovering over KDE's systemsettings icons to see "hints". When I go over one icon, it's OK, when I move the cursor to another one, the old disappears, but not smoothly. It's still blinking. This may be a completely different story though.

Can you please just hit one bug at a time in future! ;-)

Are you now able verify whether your issue was DRI3 specific?

I am going to guess that this was the expensive implicit fencing that mesa required for dri3.
