[Bug 28426] hardware cursor corruption with radeon+kms

https://bugs.freedesktop.org/show_bug.cgi?id=28426

--- Comment #6 from Roger Luethi rl@hellgate.ch 2011-08-17 03:06:17 PDT --- Attachment 36107 (DVI-0-cursor-broken.jpeg) looks like what I am seeing.

Radeon HD 4650 Radeon driver 6.14.2 no composite

I have not found a way to trigger it, it just happens after a few hours working on a desktop.

1) the cursor corruption seems to occur when the cursor crosses the boundary between the two displays of a dual-head setup

2) restarting X does not get back the regular cursor; it stays corrupted until the machine is rebooted

3) I did _not_ see this problem with a Radeon X300SE on an almost identical software setup
