Bug Description

Please watch the attached video of this bug in action; it is worth a thousand words.

When I have an external monitor hooked up to my laptop, it corrupts my ability to access application menus for windows that are opened on my laptop's native monitor.

My laptop monitor is at 1440 x 900 (16:10) resolution. The video shows this monitor exhibiting the behaviour. Watch the menu disappear before I can click on any menu option!

My external monitor is at 1920 x 1080 (16:9) resolution. Application menus are accessible just fine on this monitor.

If I unplug the external monitor, the native monitor stops exhibiting this misbehaviour.

As you can see, in the attached video, I can't move too far right before the whole menu loses hover-focus and goes away. I've been putting up with this for months; please help!

Thank you for your bug report, does it happen every time? is that specific to firefox?

No this is not specific to firefox; right now it is still doing it for any application on my laptop's LCD, but it doesn't do it if I move that same app over to monitor #2 (an external).

It doesn't always do it. It may be happening after I come back from suspend.

It was doing it when I wrote my previous message, and that was a session that was once suspended and later resumed. I just restarted, though, and now it is NOT doing it.

I just suspended, and then resumed again; it is working fine. So, my suspend-theory may have nothing to do with the reason it occurs when it does indeed occur.

This only happens when my laptop is hooked up to an external monitor. It does indeed happen every time this is the case (for all applications). See the video I posted initially (above).

When the eternal monitor is hooked up, it is not it that exhibits this problem; it is my laptop's monitor that shows this behaviour. If I unplug the external monitor's hdmi cable, the problem ceases.

Can anyone offer a suggestion on this? This hasn't gone away.

hmm, I have tried to reproduce the issue with a multimonitor setup neither my laptop nor the external screen exhibit this behavior. so it' also dependent on some other condition as well.

I can reproduce this - and I have a workaround!! It is to do with the positioning of the displays of different heights relative to each other.

Just to add - this is a very very frustrating issue if you encounter it. [Although as a side effect, it now means I use the HUD a little.]

I think Greg is right.

Try to reproduce this by making the external-monitor have a much higher resolution than your primary-monitor, and in the display-gui, try moving one monitor's "altitude" (vertical positioning) a little higher than the other and then try it "flush with tops" , and then try it "flush with bottoms". One of these positioning combinations will likely reproduce this bug in your multi-monitor set-up as well.

This remains an issue. If both monitors are NOT positioned flush-to-top (as shown in the attachment), the bug persists.

For example, if you have your monitors positioned flush-with-bottom (see attachment). You can reproduce this bug.
