Xorg 100% CPU during scrolling gnome-terminal

Could you please recheck it with Gutsy Final Live CD? In Gutsy i810 driver is deprecated and intel driver is used instead.
Xinerama doesn't work anymore with new Intel driver since xrandr is used instead.

No reply, closing the bug.

Confirmed using Ubuntu 8.04 desktop i386 and the intel Xorg driver.

Daniel, simply confirming the symptom when using -intel is insufficient for troubleshooting this. You must attach your Xorg.0.log and xorg.conf when reporting X bugs. You must also indicate what steps you used to reproduce the issue - for instance, were you also trying to use Xinerama, and the rendition driver? Were you using compiz or not? Is your hardware identical to the original reporter (an IBM Thinkcenter)? If not, you must indicate what your hardware is as well. etc. See http://wiki.ubuntu.com/X/Reporting for directions on how to report X bugs.

Unfortunately I have since got rid of that hardware. However even with my new hardware (Nvidia NVS290), the issue is trivial to reproduce; with and without compiz. Compile the below C program and watch the CPU usage of Xorg. It's totally unacceptable to anyone with programming and graphics knowledge...

#include <stdio.h>
#define LINES_PER_SEC 100
int
main(int argc, char *argv[])
{
        int n;
        for (n=0; n < 10000; n++)
        {
                usleep(1000000/LINES_PER_SEC);
                printf("Hello world %d\n", n);
        }
        return 0;
}

Changed component to Xorg since this bottleneck is obviously not just intel. I haven't attached any other details because I now believe the resolver has ample information to reproduce the issue.

sounds more like a problem in the vte engine gnome-terminal uses.

May someone having hte issue forward this upstream to bugzilla.gnome.org? for forwarding instructions please have a look to https://wiki.ubuntu.com/Bugs/Upstream/GNOME ; leaving this as incomplete until that, thanks.

any news about this?

could you try if that's still an issue in jaunty? the bug should be sent to bugzilla.gnome.org by somebody having the issue

Confirming for Jaunty. Scrolling is still horribly CPU intensive (in ALL apps, not just gnome-terminal).

Thank you for taking the time to report this bug and helping to make Ubuntu better. I noticed that the package version your bugging is updated in Maverick. Please update via www.ubuntu.com repost a detailed error report, and update the bug status. Thanks!
