I use Gentoo as a guest inside VMware Workstation 7, and since I use it with KDE 4.3.3 and VMWare does not yet support 3D-acceleration, I have activated compositing via XRender to have my panel transparent. When I have konsole open and click on it on the panel to work with it, X will crash very often and I find myself again with gdm (I use that one instead of kdm). Even if it won't crash one time or another, I can reproduce it via clicking the task manager item, minimising the window and clicking on it again. After a certain amount of tries, X will crash for sure. I have tried with several themes and widget styles, but for now it seems that this bug happens when XRender is enabled. When it is disabled it hardly ever happens, well it did happen one time, but I tried to reproduce it very often and without XRender it happens almost never, and with XRender I can reproduce it always. Reproducible: Always Steps to Reproduce: 1. Activate compositing with XRender as rendering method 2. Open konsole and minimise it for now 3. Click on the panel to maximise it 4. If it hasn't crashed yet already, minimise it again and repeat step 3, in my case it always crashes in one of the next tries Actual Results: X crashes, gdm screen comes up Expected Results: No crash, konsole should maximise normally I use VMWware Workstation 7.0.0, full version, no longer the release candidate. I can reproduce this bug without any other programs running except those of the system.

I found out right now that this happens also to gnome-terminal when I open it inside KDE. But only terminal emulators seem to be affected, I have tried with lots of other programs. So I added this to the summary now. Everything else I said for konsole is valid for gnome-terminal, too.
Created attachment 223295 [details] -g -O0 backtrace of /usr/bin/X after SIGSEV
Same here, but without vmware, plain nvidia-drivers running, compositing via OpenGL. NVIDIA GPU Quadro NVS 140M (G86) on Lenovo T61 xorg-server-1.6.5-r1 (gentoo) nvidia-drivers-195.36.03 (gentoo) pixman-0.16.4 (gentoo) kernel 2.6.33-gentoo Problem also occurred with pixman 0.17.2, different nvidia-major versions (195, 190, 185, ...) and different versions xorg-server and/or kernel. I have never had any problems running gnome/compiz-fusion, but I really prefer using KDE if possible. I've attached a gdb-backtrace with mainly pixman-calls on the stack.
I forgot: Had this problem at least with KDE 4.3.x and still have it with 4.4.1
(In reply to comment #3) > Same here, but without vmware, plain nvidia-drivers running, compositing via > OpenGL. According to the stack trace from attachment 223295 [details] the crash happens inside the nvidia driver. Please open a separate bug for that. Only post information about your issue here after it becomes clear that this is actually the same bug (not just triggered by the same actions).
Is this still happening with konsole-4.4.2?
OK, seems we have two different issues here: 1) terminal emulator plus xrender crashing X in vmware 2) terminal emulator plus xrender crashing X (nvidia-drivers) Neither seems to be a kde or gnome issue, so I'll remove the cc's, but add the vmware herd. Please move issue 2 to a different bug.
It seems to be ok now with KDE 4.4.3, so I change status to Fixed.
