screen becomes twisted when opening firefox 3 browser after using compiz fusion

[Jngoi]

Binary package hint: firefox-3.0

When Compiz fusion is enabled and the features utilized ( expo, etc.) and then Firefox 3 browser is opened the screen twists and looks like a static display then returns to normal. My device used is an eee pc 701 and I am using Ubuntu 8.04 Hardy Heron.

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 is this still an issue for you? Could you try to reproduce the same with Ubuntu 8.10 or 9.04? Thanks in advance.

It also happens in 8.10 on my Eee 1000, which has an Intel GMA950 as opposed to the 701's GMA900. I hadn't realised that compiz caused it, but Jngoi is right; I just tried opening Firefox with and without compiz enabled several times. It happened zero times with compiz disabled, and all the times it was enabled. I've attached a screenshot to illustrate the problem.

It doesn't seem to do any harm (noticeably low performance unusual even for netbooks and the like), but it just looks weird, and having had a computer that did it when it was about to freeze completely, I find it rather disconcerting. ;-)

On opening Thunderbird today, I realised that it affects this program as well. Can it have something to do with... XUL maybe?

This was due to Firefox not using _NET_WM_SYNC_REQUEST to let compiz know when it was done drawing so it could wait to draw it until it was ready. Firefox 3.5 corrects this problem so you should not see this anymore when using that version.
