Which application, which desktop? And can it be captured in a screenshot?

Hi Chris,

Applications:
Oxygen XML Editor 12.2 using latest jdk 1.6.0 (get the trial here: http://www.oxygenxml.com/)
Squirrel SQL Editor 3.2.1 (get it here: http://squirrel-sql.sourceforge.net/)
Desktop: XFCE 4.8 or Trinity 3.5.12
Got a ScreenRegion dumped with xwd, see attachment.

Regards,
Nic

Given that I have to wait for a trial key, you're going to have to
convince me that it is not simply the application mishandling a NoExpose.
What are the steps to reproduce within Oxygen XML Editor? Can it be
reproduced within the help system, which is all I can access at the
moment? Can it be reproduced in any other application using a different
toolkit?

Chris, I'm getting similar render issues with XFCE and openbox. I use 2.6.39.3
kernel + git head driver (--enable-sna).

I got screen corruption accross all the apps (xfce-terminal, im psi, xfce4
panel, firefox). Not all are text related, e.g., xfce4 panel gets corrupted in
pager (workspace switcher where no text is).

My HW is Lenovo T420. 00:02.0 VGA compatible controller: Intel Corporation 2nd
Generation Core Processor Family Integrated Graphics Controller (rev 09)

I gave a try to 3.0 kernel but problems were even worse. Playing video using
XV gave me random framents of video accross whole desktop :(

Also, is it a bug that xrandr does not report eDP and DVI ports? (the first
one is located on the NTB itself and dock, DVI is located on the dock only.)
xrandr reports only VGA1 and LVDS1 ports. I have optimus variant but
I switched to Intel only in BIOS.

Its most likely they aren't wired to the Intel chip at all, just the nvidia.

Yeah that's pretty common.  On my Vaio, I can get DDC bits from the
HDMI port with the Intel display controller, but can't actually light
it up.  I guess it's cheaper to do that than to wire up a full MUX for
the port.

Yeah the combined nvidia/intel driver detects the DDC and switches to
the nvidia driver.

I know xfce4 has the choice of a compositor, do you have it enabled? Is
it possible to capture the corruption in a screen shot?

This is to starting to sound quite serious. Is this just an excerbation
of 2.6.39 behaviour or is it an entirely new failure mode?

Oh, I forgot to answer this one. XV is just fine with 2.6.39 and the same git
head driver as tried with 3.0.0.

well, it is not :( 

this is screenshot of XV corruption with 2.6.39 kernel.

is there anything I can do in this issue? At least create bugzilla record? I'm
capable of some debugging but not sure where should I start..

I got another observation. Videos played in firefox from youtube do not get
refresh. Playback is only visible if I move another window on top of the
firefox and its subwindow with video content.
