Closing KVM window requires clicking the X twice

[Mackenzie Morgan]

<landley1> kvm in 10.04 LTS has a bug: you have to click X to close twice.
<landley1> The first click is ignored.
<landley1> If I launch it, click on the window to give it focus, and hit alt-escape to exit the grab, then it needs two clicks to kill it. (even if I switch focus to something else and come back.)
<landley1> And if I click on it to give it focus, alt-escape to exit grab, click X once, and then give it focus and escape the grab again, I'm back to needing two clicks on X to kiill it.

10.04
amd64

More details: this is xubuntu x86-64.

If I just launch kvm and immediately kill it, it exits with one click on the X. But if I clock on the display area to let KVM do a mouse grab and then alt-escape out of the mouse grab, afterwards the KVM window ignores the first click on the X. (Even if I switch focus to another window and switch focus back in between doing so, the first click on the X is always ignored after KVM's done a mouse grab.)

In fact, if I grab-and-escape, the click the X once, and then grab and escape again, it's back to ignoring the first click on the X and thus needing two clicks on the X to kill the window.

Thanks for taking the time to report this bug and helping to make Ubuntu better.

Unfortunately I won't be able to try to reproduce this this week or next. If you are able to reproduce this in a standard ubuntu 10.04 LTS with classic desktop, that would be helpful information. Otherwise, I will try to reproduce in xubuntu 10.04.

Just reproduced the same behavior in kvm natty.

More interesting:

enable focus-follows-click in metacity.

click on the kvm display area to grab the mouse, hit ctrl-alt to release, then go click on another window: you have to click twice to focus it!

(Note this is with metacity in 'classic desktop')

(Same with qemu in unity/compiz)

Using vnc+gvncviewer, the same thing does NOT happen. So presumably this is a bug either in ui/sdl.c, or in the SDL libraries.
