Hi,<br>
<br>
I am runnig Gentoo Linux on a AMD64 machine using openbox<br>
as my preferred windowmanager.<br>
<br>
Recently with an update of the system beside other things<br>
the nvidia-drivers and the xorg-server were updated.<br>
<br>
Versions:<br>
(tried all of them)<br>
x11-drivers/nvidia-drivers-304.121<br>
x11-drivers/nvidia-drivers-337.12<br>
x11-wm/openbox-3.5.2-r1<br>
x11-wm/openbox-9999 (Gentoo nameing for "developper snapshot)<br>
<br>
Openbox is started via slim (login manager), which executes<br>
autostart.sh, which (beside other things) mutt in a urxvt<br>
terminal.<br></blockquote><div><br></div><div>Do you run a compositor in your autostart like xcompmgr or anything like that?</div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

Openbox is configure to have 8 desktops, throw which one can<br>
circle back and forth :)<br>
<br>
The the problem arises after starting applications, which uses<br>
opengl/direct rendering/cuda or such things:<br>
<br>
For example: After mutt starts, I switch von desktop to the left<br>
(going from desktop 1 to 8).<br>
There I start me-tv, a dvb-t tv application.<br>
When I switch back to 1 (going to the right), the window decorations<br>
of me-tb remain on desktop 8 but the video itsself does not disappear<br>
even mutt becomes the focus.<br>
<br>
Now I click on mutt, go back to 8 (desktop with me-tv running) and<br>
back to 1 (mutt) and the problem "has gone" (the effect is no longer<br>
visible).<br>
<br>
Then I go to desktop 2 (to the right).<br>
I start Blender (another heavy opengl/rendering user) and start<br>
rendering. Regardless which window has the focus and to what desktop<br>
I will change: As soon Blender updates the rendering window, I got<br>
fragments of it thrown onto the current desktop makeing it complete<br>
graphical garbage. ^L unfortunately does not work on graphical<br>
displays... ;(<br>
<br>
I recompiled everything I could find which is dependant of the<br>
nvidia-drivers and does not help. Since I tried very old and very new<br>
versions of that driver I dont think, that this driver is "guilty"...<br>
<br>
As a test I installed fluxbox and the problem went away.<br>
<br>
But I dont want fluxbox and want my openbox back.<br>
<br>
Any ideas what I can do further to eliminate that problem?<br>
<br>
Thanks a lot for any help!<br>
Best regards,<br>
mcc<br>
