Nouveau - May 2010 - [Bug 28152] New: corruption in FVWM window decorations

https://bugs.freedesktop.org/show_bug.cgi?id=28152

           Summary: corruption in FVWM window decorations
           Product: xorg
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau at lists.freedesktop.org

Screenshot (incorrectly rendered)

On an AGP fx5700 (NV36) card, I'm experiencing rendering glitches in
FVWM's
window decorations on nouveau.  The artifacts are completely consistent:
exactly the same glitches occur on every single window.

These glitches do not occur with other drivers, and I'm certain they
didn't
occur in nouveau last time I tried it (but this was well over a year ago).

Attaching screenshots since pictures say 1000 words.

Kernel log

The top part of the log unfortunately got cut off due to log buffer overflow
before the boot process could save it, but all the nouveau stuff is there.

I've increased the log buffer size, so I can send the full log next time I
reboot, if necessary.

It appears that this bug report has laid dormant for quite a while. Sorry we
haven't gotten to it. Since we fix bugs all the time, chances are pretty
good
that your issue has been fixed with the latest software. Please give it a shot.
(Linux kernel 3.10.7, xf86-video-nouveau 1.0.9, mesa 9.1.6, or their git
versions.) If upgrading to the latest isn't an option for you, your
distro's
bugzilla is probably the right destination for your bug report.

In an effort to clean up our bug list, we're pre-emptively closing all bugs
that haven't seen updates since 2011. If the original issue remains, please
make sure to provide fresh info, see http://nouveau.freedesktop.org/wiki/Bugs/
for what we need to see, and re-open this one.

Thanks,

The Nouveau Team

This bug did not magically fix itself.  The corruption persists exactly as in
the screenshots posted over 3 years ago.

Thanks for re-checking!

Please also include a full kernel log (with a recent kernel).

And am I reading that right, xorg 1.4? Not 1.14? If so, it'd be nice to
exclude
some sort of API change issue with e.g. EXA in the interevning 6 years since
1.4's release.

Not hard to do, all I need to do is look at the top of any window :P
> Please also include a full kernel log (with a recent kernel).
I built 3.10.8, I will try it tonight to get the log...

You are reading it right, but it was written wrong!  Server version is
1.14.2.901.

Kernel log

Here's the log from the freshly minted 3.10.8 (of course the graphical
problems
are still present)

Naturally I just popped the NV34 out of my system and forgot to test this out.
For next time that it goes in... all I have to run is fvwm? Or is it fvmw2?
fvwm95? Do I need to set up some sort of theme? Do you have some sort of
compositor situation going on?

--- Comment #11 from Ilia Mirkin <imirkin at alum.mit.edu> ---
I loaded up fvwm (2.6.5) on my NV34, and it all seemed fine. However it was a
much more twm-y experience than I remember fvwm being. Perhaps you can share
the requisite theme/where I can find it, so that I'm able to repro the
issue?

--- Comment #12 from Nick Bowler <nbowler at draconx.ca> ---
Right, the default window decorations for FVWM are not much to write
home about.  I'll try to bundle up my specific theme configuration into
something you can (hopefully) use.

I don't know if any of them exhibit the same problem that I have but in
the meantime you could perhaps try fvwm-themes which has a bunch of
different window styles (http://fvwm-themes.sourceforge.net/)

--- Comment #13 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Potentially of interest to you, here's something that helped a lot in
tracking
down some rendering issues on NV1x:

rendercheck -f a8r8g8b8 -t blend,composite,cacomposite

In the nv1x case, some of the cacomposite stuff was broken. If this all works
out, try other formats, or other tests. The gradient test fails for me on all
hw I've tried it on, so don't worry about that one.
