Tearing when any compositing manager started

Anticitizen · 2014-11-11 12:00:38

I'm using openbox + tint2 panel, and I have a problem: When I turn on any compositing manager(compton/xcompmgr/cairo) video starts to tear (I lose Vsync). Even, when I add --vsync option it still tears. I want to use compositing manager, but how to set it up to stop it from causing tearing.
I'm using Open Source radeon driver.
This is my 20-radeon.conf

Section "Device"
	Identifier "vga"
	Driver "radeon"
	Option "AccelMethod" "EXA" 
	Option	"SWcursor"              "off" #software cursor might be necessary on some rare occasions, hence set off by default
	Option	"EnablePageFlip"        "on"  #supported on all R/RV/RS4xx and older hardware, and set on by default
	Option	"RenderAccel"           "on"  #enabled by default on all radeon hardware
	Option	"ColorTiling"           "on"  #enabled by default on RV300 and later radeon cards
	Option	"EXAVSync"              "off" #default is off, otherwise on. Only works if EXA activated
	Option	"EXAPixmaps"            "on"  #when on icreases 2D performance, but may also cause artifacts on some old cards. Only works if EXA activated
	Option	"AccelDFS"              "off"  #default is off, read the radeon manpage for more information
EndSection

You could try

Option "EXAVSync" "on"

This might help but you could take a performance hit. There is more information on Xorg + radeon drivers here: http://www.x.org/wiki/RadeonFeature/#VSYNC

What specific graphics card do you have?

Arch Linux
