Drag to top fails to maximise window, leaves translucent effect displaying

[Sam Brightman]

I start a terminal with my session, and it doesn't remember its position. So I try to drag the frame to the top of the desktop to maximise it, and sometimes get the situation shown in the screenshot. The translucent effect stays in place and the window does not maximise, although the application and desktop remain usable. Grabbing the terminal's title again will allow the situation to be reset back to normal (effect goes) but will not maximise by dragging until released and dragged a third time.

I don't not remember having this problem in 11.04.

[Omer Akram (om26er)]

have you updated each and everything in Ubuntu 11.10 i.e. are all updates in update manager applied? If so is that 100% reproducible issue even after relogin/restart?

[Sam Brightman (sambrightman)]

Yes, all updates applied and happened more than once after restart. Not sure on exact way to reproduce though.

[Sam Brightman (sambrightman)]

It is certainly possible to reproduce a "not maximising" behaviour by playing around with the trigger point, but the effect also doesn't show (i.e. can drag to top with nothing happening). It is also possible to trigger a maximise without the effect showing up.

Both initially seemed to be quite easy to do with a terminal window, but the former is not reproducing anymore. I'm not sure if this is intentional behaviour. I haven't been able to trigger the translucent effect triggering without maximising, but perhaps the behaviours are related.

No maximise (not 100%):

* move slowly over border
* flick back and forth

Maximise without effect:

* send terminal to the left-half position (half-screen effect shows)
* now pull it to the top (maximises without effect)
