8086:2a42 [Lenovo ThinkPad T400] xfwm4 displays window borders visually glitched

[b3nmore]

Since sna acceleration of the intel display driver is enabled by default, sometimes windows have visually glitched borders.

WORKAROUND: Switch to uxa via xorg.conf .
WORKAROUND: Disable compositing in xfwm4.
WORKAROUND: Replace xfwm4 with mutter or metacity.

Status changed to 'Confirmed' because the bug affects multiple users.

[penalvch (penalvch)]

b3nmore, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .

If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report:

apport-collect -p xserver-xorg-video-intel REPLACE-WITH-BUG-NUMBER

Please note, given that the information from the prior release is already available, doing this on a release prior to the development one would not be helpful.

Thank you for your understanding.

rather than the Ubuntu one please.

Ubuntu won't be using xfwm4 ;)

[b3nmore (b3nmore)]

I've played around a bit with the trusty daily image. So far I couldn't trigger any heavy distortions. The stippled window borders (c.f. attached screenshot) however still do occur occasionally (but with reduced frequency than before).

b3nmore, thank your your comment. When you were performing the apport-collect did you have xdiagnose installed?

If so, did you get the following message and click yes:
"Your display manager log files may help developers diagnose the bug, but may contain sensitive information such as your hostname. Do you want to include these logs in your bug report?"

I should mention, that in contrast to the original report, the stippled window borders appear now independent of the compositor state (on or off).
I've also tested xfwm4 in combination with compton (standalone opengl compositor) with the same result: occasional appearance of stippled borders.

[penalvch (penalvch)]

b3nmore, thank you for performing the requested test. Given the display distortions have ceased, let us refocus onto the window border striping.

Regarding this, so that a more updated version of the xorg stack may be tested, could you please test for this via https://launchpad.net/~xorg-edgers/+archive/ppa?field.series_filter=trusty and advise to the results?

[b3nmore (b3nmore)]

I've updated the packages from the mentioned ppa. Additional to the border issue I get now quit frequently character distortions (cf. the second "(II)"- line in the screenshot of the terminal window) in different programs.

Please note (cf. comment #31), that using a compositor or not does not seem to have any influence anymore. In both cases I get the striped border and now the character distortion; i.e. disabling the compositor isn't a valid workaround anymore.

[penalvch (penalvch)]

b3nmore, thank you for performing the requested test. In order to streamline this report, it will only focus on the issue of the striped borders, as that is what is reproducible in Trusty. Hence, the issue you are reporting is an upstream one. Could you please report this problem through the appropriate channel by following the instructions _verbatim_ at https://01.org/linuxgraphics/documentation/how-report-bugs ?

Please provide a direct URL to your bug report once you have made it so that it may be tracked.

Thank you for your understanding.

[b3nmore (b3nmore)]

Another annotation: I have the striped borders issue also on my desktop system: xubuntu 13.10, Intel i5-4570S with integrated hd4600 gpu. So I guess this issue isn't limited to a single set of hardware.

[penalvch (penalvch)]

b3nmore, regarding your desktop, so your hardware and problem may be tracked, could you please file a new report by executing the following in a terminal:
ubuntu-bug xorg

For more on this, please see the official Ubuntu documentation:
Ubuntu X.Org Team, Ubuntu Bug Control, and Ubuntu Bug Squad: https://wiki.ubuntu.com/Bugs/BestPractices#X.2BAC8-Reporting.Focus_on_One_Issue

Thank you for your understanding.

This should have been fixed by the upgrade to 2.99.909, now 2.99.910.

[b3nmore (b3nmore)]

> This should have been fixed by the upgrade to 2.99.909, now 2.99.910.

Unfortunately not for me (c.f. attached screenshot). I still can reproduce the border issue (with and without the compositor) quite frequently.

[b3nmore (b3nmore)]

> > This should have been fixed by the upgrade to 2.99.909, now 2.99.910.

Oh, wait. Did this mean by upgrading *from* 2.99.909 to 2.99.910? If so, please ignore my previous comment, since I'm clearly running 2.99.909.

[b3nmore (b3nmore)]

Even 2.99.910 did not fix the issue.

[b3nmore (b3nmore)]

Ok, thats weird: I still get the striped borders occasionally on a fully updated trusty, but only when I use the Greybird-compact xfwm4 theme (or so it seems). I replaced therefore all the left-*, right-*, bottom-* xpms of the theme with those of the normal Greybird theme and didn't see striped borders anymore.
It seems, that the intel driver with sna enabled chokes some times on the repeated use of those particular pixmaps.

[b3nmore (b3nmore)]

This is now fixed upstream:
