Description jinliangx.wang 2014-09-15 08:18:00 UTC
==Bug detailed description==
Connected with multi display(like eDP, DP, and HDMI), start X, then change the rotation of any two displays for many times, sometimes the original x window would not be refreshed ( x window would not change rotation, or there would appear 2 x winodws, one normally change the rotation, another one keep at last location. )  

Low reproducible, is less than 10%.
So has not yet been determined whether belong to regression.

==Reproduce steps==
1. xinit &
2. xrandr --output eDP1 --rotation (left|right|inverted|normal) --output DP1 --rotation (left|right|inverted|normal)

It should be regression, but because its' low reproducible, it's hard to find the good commit.

In all likelihood this is a kernel bug.
