The whole screen is cleared to black when using the workspace switcher (wall plugin)

I can't reproduce that with the latest unity and natty update today. I run on an old ATI (R300).

Further to the bug description, Didier really confirmed that the issue is reproducible only when the unity plugin is activated, ie it doesn't happen with just compiz and the regular workspace switcher plugin.

Lowering the priority a bit, as it's not a crasher / major impact on the shell. Yet, it's a regression.

I cannot reproduce this with the latest compiz and unity in natty as of today. I'm using an intel chip (GM965). Perhaps this is an nvidia specific issue?

seems unity is conflicting with the lightning opengl effect of compiz on some cards. After discussing with jason and sam, better to disable it as the effect isn't really used.

This bug was fixed in the package compiz - 1:0.9.2.1+glibmainloop4-0ubuntu4

I can still reproduce this with the latest Compiz. I use and NVidia 8800 GTX card.

I can report that the issue does not happen on my Dell mini 9 (Intel GMA 950) + Natty. This could be an NVidia specific issue.

@Jay: you should deactivate the lightning effect conflicting with unity. You can unity --reset to reset to the new default settings.

Didier, did you mean to say "lighting" rather than "lightning"? If not, how does one change the "lightning" effect? I can't seem to find it. If lighting, what should be altered there?

Thanks.

Indeed, it was lighting.
