Description schaedpq 2006-06-14 10:47:07 UTC

For some time I have an issue with kwin (apparantly) randomly crashing due to a segmentation fault. According to the backtrace, that happens in QPainter::drawTiledPixmap.
I observed this in qt-3.3.4-r8 and qt-3.3.6-r1 with kdelibs-3.5.2-r6 and
kdebase-3.5.2-r1 (and I think it happened with kdelibs-3.4.3-r1 and kdebase-3.4.3-r1 as well).

I have some difficulties to reproduce this issue, it happens now and then. Sometimes several times a day, sometimes it does not happen for days. The backtrace is always the same:

I noticed some similarities with bugs #107179 as the effect is similar and the crash occurrs in both cases in QPainter, but in different functions.

For some time I thought it may be an issue with the hardened gcc and may be related to bug #126896 but kwin also crashes, if qt is compiled with a vanilla gcc, although I have the imperession, that it happens less often.
The crash that produced the backtrace above happend while using a qt compiled by a vanilla gcc (i686-pc-linux-gnu-3.4.6-vanilla).

Comment 1 Sérgio Luís 2006-08-02 14:41:28 UTC

I had some crashes with kwin (which i could reproduce). Now that i upgraded to kde 3.5.4 they are gone. Can you see if kde-3.5.4 resolves your problem?

Assuming this is not a problem with KDE 3.5.4. Otherwise reopen please.
