mutilated preview window

Attaching the preview window as jpg file

Testing the same in a *xfce* session:

After exiting and starting xsane again, the preview window remains presented (in a correct manner). 

It seems the problem is a gnome-shell problem.

I get rid from the described behaviour by starting xsane inside a terminal window and not by the gnome-shell favorite bar.

This is strange. Would you please attach your (possibly compressed/gzipped if needed) ~/.xsession-errors to this ticket? Thanks.

Another one: Please switch (temporarily) to forced fallback mode -- I have a hunch that this is related to GNOME3 using compositing. To do that, go to "System Settings -> System Info -> Graphics" and switch "Forced Fallback Mode" to "On". Then logout and login again, and check if xsane behaves in the same fashion. Thanks.

In the fallback mode I can't reproduce the described behaviour. But If switching off the fallback mode and then logging in again and starting xsane (by the favorites bar),  the preview window is again mutilated.

Kind regards

I'll assume that compositing triggers this broken display of the preview window then. Changing component to mutter for further investigation.

Good to hear, because I have more some apps whose behaviour strongly depend on the usage of mutter or not.

I cannot rproduce the described behaviour with mutter-3.2.2-1.fc16.x86_64.

Hi folks. I just had this error occur on my x86_64 Fedora 17 install, using mutter-3.4.1-4.fc17.x86_64:

Should this bug be reopened or shall I file a new one?

Same problems in F20 (xsane-0.999-12.fc20.x86_64)

I forgot to say: I'm working with mutter-3.10.4-2.fc20

Downgrading to mutter-3.10.4-1.fc20.x86_64 helps :-)
