Bug #: 52330
Summary: Triple monitor desktop intermittent slow updates
Classification: Unclassified

Version: git
Platform: x86-64 (AMD64)

Status: NEW

log when performance is slow, prints from 3154.543 and on are when I resize the
desktop and back
Been trying to get to the bottom of this and am now running with xf86-video-ati
module from git so should be able to add some debugging if needed to figure
this out.
Bootup with 3 screens enabled (left-to-right: 1200x1920 + 2560x1600 +
1200x1920) on Radeon 6850 leads to very slow screen updates. However, changing
to just 2 monitors and then back to 3 seems to solve the problem most every
time for that session.
