scrolling in evolution or firefox (or others) create glitches on the window

[RollingFred]

I'm using Ubuntu 7.10 on an IBM T61 with nvidia graphic card.
I installed proprietary Nvidia drivers (allowed me to configure Twinview correctly) using Envy. I had the problem before that (using nv-glx-new). I have the problem when using my two external monitors, as well as when using my laptop panel only.

When scrolling using the scrollbar on the right side of a Firefox window or Evolution, or when using the arrow keys, or when using the mouse wheel, the window doesn't refresh properly, and the same line seems to repeat multiple times. It's scrolling but the display is messy.
When I use page down/page up keys, or when I click above or below the elevator in the scrollbar, the window is refreshed properly.

I have that problem mostly in every windows allowing scrolling. I'll scroll in this page a little and will attach the screenshot.

When clicking on a different window, the window with problems seems to be refreshed and display correctly.

Feel free to ask anything, I'll do my best to forward any information.
Thanks

Is this still an issue?

[RollingFred (fred-peiffer)]

Yes, still an issue. Since then, I upgraded to Ubuntu 8.04 and am up to date with all the updates. I'm still suing the same config (nvidia proprietary, envy, as twinview is working properly this way).
If I don't use compiz and the cube, everything is fine. As soon as the cube and compiz are enable for effects, the artifacts appear.
If I would to do a screenshot, it would be the same as above. Thanks.

Why is this low priority?

The issue still persists with IPP=1.

The "fix" for this is to set IPP=2 with nvidia-settings, but that casues yet _another_ issue!

[RollingFred (fred-peiffer)]

Beat me.
I've been dealing with this issue since Ubuntu 7.10 upgrading each time
hoping it would be fixed.
My Ubuntu 8.04 machine is my work machine, I'm developing on it everyday and
the glitch is annoying especially when doing demo.

I really hope it gets fixed soon...

I too am on a T61 and have seen this off and on. I seem to get it when I resume from suspend. I upgraded the video drivers and compiz:

Performance is good, but the artifacts are horrible.

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue for you. Can you try with the latest Ubuntu release (maybe live CD)? Thanks in advance.

If it does, can you include the following files:
~/.xsession-errors
 /var/log/Xorg.0.log

and the output of lspci -vvnn.

Also try to see if the bug happens with the default settings. To get the default settings, install "compiz-config-manager", launch it and then go to "Preferences" (left bottom corner) and click on the "Reset to defaults" button.

We're closing this bug since it is has been some time with no response from the original reporter. However, if the issue still exists please feel free to reopen with the requested information. Also, if you could, please test against the latest development version of Ubuntu, since this confirms the bug is one we may be able to pass upstream for help.

I've just recently started using Ubuntu (version 9.10) and have been having this problem. It makes dual monitor mode pretty much unusable with Compiz turned on, at least in my work environment. Oddly, though, I don't seem to have the same problem at home with the same laptop and an almost identical second monitor. [Not completely sure about that, though, as the problem doesn't seem to occur immediately after boot and I don't use my laptop in that configuration at home very often.]

Following a suggestion in this thread, I just turned compiz off and the problem immediately disappeared. Whether it stays away, however, remains to be seen! Unlike some previous posters, I had the problem with all modes of scrolling (scrollbar, arrow keys or mousewheel), not just with the mousewheel, although it's worse with the mousewheel. And I think it occurs in any application though its symptoms are a bit different depending on the app.

I attach a zip of the two requested files plus the output from lspci.

I just turned compiz back on again, set the settings to default as you asked, and the problem (after a while) is back with a vengeance. I can't seem to get a screen dump, though -- any attempt to use the window dump accessory or xwd causes an immediate redraw of the offending window, which then looks fine. Just FYI -- may or may not be relevant -- I have the impression that the issue is somehow timing related. In some cases I've seen the torn-looking window then, perhaps half a second later, have seen the bad bit get repainted OK. At other times the repaint simply doesn't happen and the problem remains.

A fix would be great, but in the meantime I'll just run with Compiz off.

Incidentally, thanks for a great support operation. So far, at least, I'm thrilled with the switch over to Ubuntu, running Windows, only when I really have to, under Sun VirtualBox.
