Yep click on any Menu,Nm-applet,Digital Clock,etc…
Popup menu pops up then leaves edge lines behind.
Can see the Vertical line on left.
Doing something like launching Firefox you can see the line disappear just before app opens.
Tried setting different settings in compositor
No matter swiitching scale method,Backend from 2.0 to 3.1 Tearing prevention off or on.
Changing decorations,desktop themes,etc… Still persists with those annoying vertical lines.
Using latest 2016.01 fresh install and is updated to this date.
and latest default open drivers on a Ati 4350 leagacy card. And never an issue like this.
Anyone with Info or fixes for this issue is appreciated.
Hmmm. Thought I tried that. But went ahead and tried.
Thanks! Seems to have fixed the ghost issue. But now annoying is switching speed of virtual desktops.
See if I can find a fix for that as like to see the tranisiton of changing Virtual desktops with my mouse wheel.
Instead of the jarring Bam! now with instant with changing Virtual Desktops.
Seems more work required on compositor.
Since multiple settings seem buggy?
Just tried middle of the slider between Instant-Very Slow and seems a trade off of no ghosting and rotating virtual desktops.
So would say solved for now I guess.
DRI 3 is now enabled by default for the opensource drivers under Manjaro.
Have you tried removing or remarking this line out in your /etc/X11/mhwd.d/radeon.conf file to see if it helps:
Option "DRI" "3"
By removing this setting the driver will default back to DRI 2.
