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.
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?
fwiw, may be worth to mention your video hardware and what driver you're using.
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. xorg-x11-drv-ati.x86_64 6.14.0-2.20110204gita27b5dbd9.fc15 kernel 2.6.38-0.rc8.git0.1.fc15.x86_64 kdebase-workspace.x86_64 4.6.1-1.fc15

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)

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. # yum list installed '*mesa*' Loaded plugins: auto-update-debuginfo, langpacks, presto, refresh-packagekit Installed Packages mesa-debuginfo.x86_64 7.10-0.29.fc15 @updates-testing-debuginfo mesa-dri-drivers.x86_64 7.10-0.29.fc15 @updates-testing mesa-dri-filesystem.x86_64 7.10-0.29.fc15 @updates-testing mesa-dri-llvmcore.x86_64 7.10-0.29.fc15 @updates-testing mesa-libGL.x86_64 7.10-0.29.fc15 @updates-testing mesa-libGLU.x86_64 7.10-0.29.fc15 @updates-testing # yum list installed '*xorg-x11-drv-ati*' Loaded plugins: auto-update-debuginfo, langpacks, presto, refresh-packagekit Installed Packages xorg-x11-drv-ati.x86_64 6.14.0-6.20110315git4d3504970.fc15 @updates-testing

No crash since march, so this bug-report can be closed for sure.
Apparently fixed by an unknown update.
