Description Dave Airlie 2011-03-09 00:03:59 UTC 
Local user installed nightly and reported that dragging windows left on his desktop resulted in corruption on-screen.

Reverting users desktop to glibc-2.12-1.19 fixed the corruption.

user was running nouveau driver with no acceleration enabled.

I'm not resposible for bugs in the X server.

Andreas,

This is a bug filed against glibc so the problem case can be reverted. It has the 3 acks, the RHEL tech lead has stated the purpose and supplied the devel_ack.

I'm not sure you really understand, so maybe you should talk to your manager before reassigning this bug to a component other than glibc. I'm assigning this bug to notting until he can resolve the issue with your manager.

Do feel free to clone this bug against pixman which is most likely the package with the issue. and we can address it in 6.2.

Subject changed, then. The X server bug has been cloned for 6.2.
