Description Reartes Guillermo 2011-03-10 15:21:17 UTC

Description of problem: When forcing the fonts DPI, kwin crashes with segmentation fault (11). The other applications are unaffected, no work
is loss.

Version-Release number of selected component (if applicable):

How reproducible: allways

Steps to Reproduce:
1. log-in, enable desktop effects (disabled by default)
2. system-settings, go to fonts and change DPI (96 to 120 or 120 to 96)
3. apply, kwin crashes (the other apps are ok)
  
Actual results:
the DPI change seems to apply. The 120 dpi fonts looks really ugly compared
to F13/F14 with 120 DPI fonts.

Expected results:
to be able to switch DPI with no error

Additional info:

With desktop effects disabled, it does not happen.
The "use anti-aliasing" was allways enabled.

Comment 1 Rex Dieter 2011-03-10 15:27:47 UTC

Fwiw, just tried on my new f15/x86_64 kde install, switching dpi did not segfault for me.

Do you have a backtrace we could look at?

Comment 2 Rex Dieter 2011-03-10 15:44:47 UTC

fwiw, may be worth to mention your video hardware and what driver you're using.

Comment 3 Reartes Guillermo 2011-03-10 16:05:44 UTC

AMD HD5670, default driver (radeon/ati i think), previously i opened the 
following bugreport

Bug 683825 - Graphical corruption/artifact in KDE with ATI HD5670 (1002:68d8)

I will try to install debuggin symbols and get one.

I'm gonna guess that's inside mesa somewhere.

Comment 7 Reartes Guillermo 2011-03-10 23:18:07 UTC

There is more stuff:


workspace appearance --> window decoration
  -->oxygen(only when comming from another), laptop, tabstrip BAD (the other  seems ok)


workspace behaviour --> virtual desktops
  --> desktop effect animation
    --> no-animation, desktop cube animation, fade desktop BAD (slide is ok)

application appearance --> style --> widget style
  --> plastique, cde, cleanlooks BAD (GTK + style, Ms windows 9x, motif, okygen, qtcurve are ok)

Comment 20 Reartes Guillermo 2011-03-15 14:35:32 UTC

If Desktop Effects are ENABLED, but the compositing type is changed from 
OpenGL to XRender, it does not happen. (XRender is slower)

So it only happens when DE is ENABLED and Compositing_Type is set to OpenGL.

With the latest updates i was not able to reproduce the crash.
Previously these system-settings crashed:

* Application Appearance > Fonts > change dpi to 96 or 120
* Workspace appearance >  window decoration > oxygen(sometimes), laptop, tabstrip 
* Workspace behaviour > virtual desktops > desktop effect animation
  > no-animation, desktop cube animation, fade desktop 
* Application appearance > style > widget style > plastique, cde, cleanlooks

I will test it again in the weekend, but it seems ok now.

No crash since march, so this bug-report can be closed for sure.

Apparently fixed by an unknown update.
