OR windows can go awol

[Antoine Martin]

Reproducible using gnome-terminal: simply move through the drop down menus quickly until one of them goes missing.
A "the window (...) is not composited!?" message shows up in the logs.

This a server issue and re-connecting the client does not solve the problem..

377 the window <OverrideRedirectWindowModel object at 0x1d91aa0 (wimpiggy+window+OverrideRedirectWindowModel at 0x1751760)> is not composited!?

I think the problem comes from here:

found existing model (...) for (...)

Which comes from r2304 and our attempts at dealing with gtkperf more gracefully..

[Antoine Martin]

The workaround is in r3071.
In the review, I found more problems:

• handlers not getting disconnected: fixed in r3070
• window unmanage code not firing when setup fails: fixed in r3069

Will test and close this ticket. This may need backports too.

But... we have lost tooltips (#262 related?), as can be easily seen by running filelight which makes heavy use of them. Bummer!

Replying to totaam:

But... we have lost tooltips (#262 related?), as can be easily seen by running filelight which makes heavy use of them. Bummer!

I'm testing r3072 and I see tooltips in filelight... They were disappearing after some time but from the first quick try I couldn't reproduce that in r3072 so it could become a bit better (if it's not my wishful thinking).

[Antoine Martin]

r3116 fixes the tooltips: it was opengl not notifying us of mouse motion events.

So maybe this ticket can be closed after all? Feedback welcome.

[onlyjob]

Looks like tooltips were broken only in opengl mode (that's why I couldn't reproduce as I was trying with "--opengl=no").

It appears to works well with r3118 so I think this bug can be closed. Thanks.
