--- Comment #1 from Alex Deucher agd5f@yahoo.com --- PRIME only works with a compositor. Make sure you are using one.

Thanks, xcompmgr fixed it

--- Comment #4 from Michel Dänzer michel@daenzer.net --- I'd argue this is actually a bug (probably in the X server): If PRIME can't work without compositing, it should enable automatic compositing for the windows that need it.

--- Comment #6 from Maxim ya.maxis11@yandex.ru --- if in /etc/environment set DRI_PRIME=1 and in /etc/xprofile set xcompmgr -c & some apps will display with artifacts (part of window freezes when scrolling)

if in /etc/environment set DRI_PRIME=1 and in /etc/xprofile set xcompmgr -c & some apps will display with artifacts (part of window freezes when scrolling)
Apps using PRIME, or others?
BTW, just xcompmgr -a should be enough, no need for -c.

others. Today I've tested with DRI_PRIME=0. Same lags. It's appear, when xcompmgr running.

That's not directly related to this bug report then. If xcompmgr -a doesn't work better, there are many other compositing managers you can try.
