Thanks.

I am going to close this bug for now. It is probably better to
(re)open a bug against nouveau, if it is still present and you decide
to go back to nouveau and assign the bug to that package. But for now
I don't see a reason to reassign it.

In either case it doesn't appear to be a bug within fvwm.

Due to the numerous bugs in the nouveau driver over the years and
the lack of bug fixes, I've been using only the Nvidia driver for
some time. I have never seen any problem with Fvwm and this driver.
So, it was probably a driver bug.

Hello,

I am just seeing if you have figured out if this was a video driver
bug or not? Do you still experience this with with fvwm 2.6.7?

Bug#675716: fvwm corrupts a sticky window over FvwmPager at desktop change

[Vincent Lefevre]

Package: fvwm
Version: 1:2.5.30.ds-1.1+local1
Severity: normal

The following sequence can trigger a display problem with my config
file (see a part of my fvwmrc below):
1. Open a GNU Emacs window where File (in the menu) is over the
   FvwmPager (where there will be a change below).
2. Set the window as sticky.
3. Change the desktop (e.g. with Ctrl-Meta-arrow).

- A part of the Emacs menu bar can be corrupted. See attached
snapshots as examples.

I think that what happens at (3) is the following: due to the
desktop switching, the contents of FvwmPager change. Normally
this change shouldn't be visible because the Emacs window is
over the FvwmPager window and is sticky, but this change is
partly done on the screen as if the Emacs window weren't there.

I can easily reproduce this bug with Emacs, Calcoo and Qalculate,
but not with some other applications, like gnome-terminal.

Note: my fvwm package is a locally rebuilt version with the
shape-hints patch in bug 588537.

My fvwmrc contains in particular:
