Description michal kaczmarski 2005-01-25 10:32:46 CET
xfwm / x.org crashes ( return to the framebuffer terminal , whole X server crashes ) 

when I using QT-based apps , xfwm / x.org crashes sometimes. ( KATE,KADU etc.)
when CPU usage is high especially. sometimes helps renincing to ~RT prior like -19 / -20 or running QT-
app in SCHED_ISO mode of cpu scheduler , but not always.

the similar problem I had when I`m used enlightenmnet 0.1.6.7.2 with xcompmgr. now with current cvs 
xcompmgr is better.

I`m not sure about the problem is related to xfwm-compositor or x.org 
My x.org = 6.8.1.902 , xfce cvs (1 day ago from now - 25.01.05 ) 

thanks & regards 
fallow

Reproducible: Always
Steps to Reproduce:
1. enable composite
2. run some qt app - KADU ( http://www.kadu.net/index.php?page=news&lang=en )  or KATE
3. make system CPU usage high , ex.compiling something , or high I/O usage
4. ***  when I trying to receive message with Kadu - x.org / xfwm crashes
5. *** when I trying to open some file with KATE - x.org / xfwm crashes
Actual Results:  
xfwm / x.org crashes

Expected Results:  
not crashing - normal work of xfwm / x.org

Comment 1 Olivier Fourdan editbugs 2005-01-25 22:00:57 CET
If you are returned to the console, it means X has died (not xfwm4), so it's a
bug in X... Not much we can do. 
Comment 2 Olivier Fourdan editbugs 2005-01-25 22:10:51 CET
Here I can crash X.org by simply running "xterm -bg black -fg white", no matter
which composoting manager is run (xfwm4, xcompmgr)

Guess you see why the compositor is disabled by default...

:( ..so I will post it in x.org bugzilla :) but composite + transparency seetings by mouse scroll is so beaty :
P :) I changed cpu scheduler , and I`m going to modyfi kadu code for compensate cpu usage by time 
delays , also to change my reiser4 system to reiser3 maybe , (crashes with high i/o usage ) .

thx and regards xfce team ;)
cheers

This is an XOrg Composite bug.
Comment 5 Jasper Huijsmans editbugs 2005-04-08 11:08:14 CEST
Not an Xfce bug.
