Text display issue with compiz-fusion+twinview

[Nicolae]

I'm trying to get my laptop set up so I can use it with my monitor, and to do so I have to use twinview since nvidia broke hotkey switching and never bothered to fix it. However, since I've been trying to get this set up, I've noticed an issue with text display. It "lags", if you will. for example, I'm copying files to my laptop now. If I switch away from that workspace, and go back, the text in the progress box is over top of itself, from where the current speed/file/etc has changed. In konsole, when someone talks on irc (in irssi), the screen "doubles", with the text both moving up as it should and then also staying put, giving me two of every line with various levels of overlap. Switching to a different tab in konsole and then back fixes it, until someone else says something.

I'm using Kubuntu Gutsy, with the latest version of compiz-fusion available in the repos+kde-window-decorator and the newest beta nvidia drivers (169.04).

I've the following plugins loaded: Negative, Expo, Desktop Cube, Rotate Cube, Viewport Switcher, Window Decoration, JPEG, Png, svg, text, crash handler, cube caps, regex matching, scale addons, video playback, application switcher, move windows, place windows, ring switcher, scale, and resize windows.

I can post any other pertinant info if you need it.

Here's a screenshot, showing the text duplication. I've set the refresh rate with ccsm to what it actually is for the external monitor (75Hz) as well, still doing it.

Man, I've been looking forever to find someone who has the same problem. I'm not running twinview, so you can rule that out. It's some issue between compiz-fusion, nvidia drivers and kde konsole. For me, it only happens in konsole, and only after I rotate the cube. It started happening on my machine after I upgraded to the nvidia 169.04 linux drivers. I really have no idea where to look to narrow down the cause. But I can say that it only occurs when I'm running the combination of konsole, compiz-fusion so it may be some kind of kde composite bug.

Well, I found it in this forum and at NVnews. The trick is to add "UseCompositeWrapper" to the device section of your xorg.conf. Fixed it for me.

Excellent, that seems to do the trick.

Thanks!
