Launcher does not hide/unhide properly in dual monitor setup

[Tal Liron]

In a dual monitor setup, where the RIGHT monitor is set up as the primary monitor, the launcher does not hide and unhide properly. (Please not this distinction: the problem does not appear if the LEFT monitor is primary.)

It seems that the mouse has to be placed EXACTLY at the edge in order for the launcher to unhide. Anywhere else close to the egde and the animation for unhiding seems to be stuck somewhere in the middle: the animation does not progress until the mouse is placed exactly at the edge.

I've tested this both with fade animation, slide animation, and fade+slide animation.

Another problem may be related: when I disable hiding of the launcher, everything gets pretty crazy and unusable! Windows all seem to slide towards the location where the launcher should be, and the desktop as a whole is unusable until autohiding is enabled again.

Thanks for the bug report. This particular bug has already been reported, but feel free to report any other bugs you find.

Sebastian, this is not the same bug as 757652! The launcher *does* appear in the correct position for me. The issue is hiding/unhiding it via the mouse. I will try to create a screenshot as suggested, although it's difficult because this is animation.

[Tal Liron (emblem-parade)]

OK, I have a screenshot for you! But it requires some explanation. :)

What you see is the border between my two monitors, with the Launcher on the left edge (as usual) of the right monitor.

The screenshot did not capture my mouse pointer, but imagine that it is right now on the middle of the BFB.

You are seeing the Launcher in the middle of fading in to full view, so it is half-transparent.

The thing is, it stays in exactly that half-transparent state until I move my mouse pointer left a few pixels, so that it would land exactly in the "hot spot" which is at the top left of the BFB. Until I move the mouse pointer there, not only is the Launcher half-transparent, but it is also not clickable. I absolutely have to hit that "hot spot" for it to become useful.

Second issue: I also reported that setting the Launcher to "never hide" mode was also broken for me (windows all got "pulled" towards the area between the two Launchers and were un-reachable). I tried to duplicate it again in order to create a screenshot for you, but this time it didn't happen, and "never hide" works OK! Maybe I changed a setting somewhere, or an update came in? I do not know. I'm glad, though, that my bug report is up, and hopefully is someone else has the same issue they can find it and help us triage.
