Description Eric Depagne 2015-05-02 08:38:49 UTC
I have set the height of the taskbar so that it displays the apps in two rows (and it's located at the bottom of my monitor). If I hover the mouse over the top row, I can then click on the tooltip to go to the application.
However, if I hover over one of the application located in the bottom row, then, the tooltip appears, as expected, but then, I can't click on the windows, since the movement of the mouse goes over the top row, and then, another tooltip appears.  

Reproducible: Always

Steps to Reproduce:
1.  set the size of the taskbar so that the taskmanager displays applications running in at least two rows
2. Hover the top row, and you can select any application by clicking on the tooltop
3. TRy to do the same with an applicaiton appearing the the bottom row, and you can't

Actual Results:  
Top row applications are the only one that can be selected from the taskmanager 

Expected Results:  
ANy applicaiton should be selectable from the taskmanager

To emphasise for the next person reading this, it's clicking on the window in the tooltip that doesn't work. Clicking on the task in the bar works fine.

No idea how we could fix this from a design perspective.
Comment 2 Eric Depagne 2015-05-12 08:44:23 UTC
Very naïve answer to David Edmundson : the tooltip is deactivated immediately when the mouse leaves the area taken by a given task in the taskbar. Would it be possible to have  delay before the disappearance? This would allow the mouse to reach the tooltip when triggered from the bottom row(s) of the taskbar, and not change anything if the tooltip is triggered from the upper row

I haven't tested it but I think the patches in bug 358930 should also fix this.

Comment 8 David 2021-10-05 00:34:31 UTC
Another solution: don't make it switch window previews when moving the mouse over a different icon than the one that was clicked.
Comment 9 Nate Graham 2021-10-05 00:57:30 UTC
You don't need click on anything to see the tooltip (for single windows, that is); it appears on hover.

I have it configured on left click and this still happens. Up to a few versions ago (at least with latte) it would not shift window previews as one moved the mouse to a different icon.

Sure but that's an option, and not the default behavior. The fix needs to work for everyone.
Comment 12 Bharadwaj Raju 2023-02-08 18:36:28 UTC
Fixed in master and 5.27 branch. I expect the fix will be there in the 5.27.1 release.
Comment 13 Nate Graham 2023-02-08 18:44:09 UTC
5.27 hasn't been tarred yet, so it'll be fixed in 5.27.0, in fact!

Comment 16 Eric Depagne 2023-02-27 09:46:18 UTC
Good day all.
I can confirm after a few tries that I can now select any window, even when the thumbnail appears on the bottom row of the taskbar.
Thank you!
