Problem does not occur while Compiz effects (Preferences->Desktop Effects-> Compiz) are turned on.

Issue occurs also on rotated primary display.

Comment 7 Matěj Cepl 2010-06-15 11:15:29 UTC
Yes, can reproduce here, but it seems like it is rather minor glitch and it tends to correct itself after a brief period of time. Agree?

Comment 8 Marian Csontos 2010-06-15 11:50:44 UTC
Minor glitch? Try working with this glitch-feature enabled.
It impacts pretty much whole GUI, Firefox, everything...

Comment 9 Lubos Kocman 2010-06-15 12:04:23 UTC
Working with this "minor glitch" is really painful redrawing is slow.

And it's not really pleasant/safe to see corrupted name of the file that you're going to remove .... like:

rm fi       .t t

Especially curses based applications suffer from this all the time while using them.

I see this as a blocker, lots of people here are using flipped widescreen to the left. And this is really a problem.

I am unable to reproduce this with:


at least not on 5-series.  I'll dig up a 4-series to confirm, but if you could retest with newer versions that'd be great

Comment 12 Lubos Kocman 2010-06-17 06:37:48 UTC

I'm always trying to be as updated as possible. And as I said this issue is also on Fedora which has most probably much newer releases ...

Comment 13 Adam Jackson 2010-06-23 16:08:18 UTC
That's not an answer.  Can you reproduce this with current RHEL6 packages, and if so, which ones?

Comment 14 Dave Airlie 2010-06-24 01:35:02 UTC
okay reproduced this or something like it on my 965gm with rotated screen, I'm not seeing it too the same extent, but I am seeing a lag on each keystroke in the terminal like a flush is missing or something.

Comment 15 Lubos Kocman 2010-06-24 13:34:20 UTC

I'm able to reproduce it with RHEL6 on following packages:


Dave could you please test it on  popup menus? (e.g. right click on desktop placed on rotated display?) Highlighting of the current item is messed up as well as redrawing in the terminal.

Comment 16 Dave Airlie 2010-06-25 01:13:19 UTC
I've built xorg-x11-drv-intel-2.11.0-6.el6 in brew.

can you test and feedback here?

Comment 17 Lubos Kocman 2010-06-25 13:06:53 UTC
Hello Dave,

the issue is now fixed. Tested on xorg-x11-drv-intel-2.11.0-6.el6.x86_64.

Thank you

Comment 18 Lubos Kocman 2010-06-29 14:55:46 UTC
Verified on:

xorg-x11-drv-intel-2.11.0-6.el6. Issue no longer occurs in this driver.
