Description Tomas Nilzon 2022-06-20 14:22:11 UTC

SUMMARY
***
If you select "Preview and Highlight Windows" in the "Settings/Tasks Actions/Hover" the first hover on an icon will activate both "Preview" and also "Highlight" the application window.
***

STEPS TO REPRODUCE
1. Open "Edit Dock" and select "Preview and Highlight Windows" in the "Settings/Tasks Actions/Hover"
2. Close "Edit Dock"

OBSERVED RESULT
1. Open any number (more than one) of application windows on the desktop.
2. Hover an icon for any of the open applications with the mouse pointer and keep the pointer still over the icon.
3. Watch the preview to pop up, and also the application window to be highlighted on the desktop.
4. Then move the pointer from the icon to the preview and back again to the same icon.
5. Watch the preview to still be displayed, and the application window to not be highlighted.
6. Then move the pointer from the same icon to the preview again and watch the application window to be highlighted.
7. Moving the pointer to and from the same preview will now also toggle application window highlight (this is how it should be). It is only the first time the pointer move to hover any icon for an open application window that behaves wrong.

EXPECTED RESULT
1. Open any number (more than one) of application windows on the desktop.
2. Hover an icon for any of the open applications with the mouse pointer and keep the pointer still over the icon.
3. Watch the preview to pop up and no highlighting occurring.
4. Then move the pointer from the same icon to the preview and watch the application window to be highlighted.
5. Then move the pointer from the preview and back again to the same icon.
6. Watch the preview to still be displayed, and the application window to not be highlighted.
7. Moving the pointer to and from the same preview will now also toggle application window highlight.

Just tested this update. It does not work as expected. "Highlight" should only occur when the "Preview" is hovered, not when the application icon is hovered. When the application icon is hovered, there should only be a "Preview" (and "Highlight" only when the mouse pointer hovers the "Preview").

nope, I thing it works just fine, especially when you are hovering a grouped task and the first hovering on the tasks shown only windows of the same tasks and hides all the rest.

Yes, I think that's a correct behavior if you have selected "Highlight Windows" only in the settings. But if you have selected "Preview and Highlight", it is more logic with a behavior as I described: When the application icon is hovered, there should only be a "Preview" (and "Highlight" only when the mouse pointer hovers the "Preview").

You can compare this with how this functionality behaves in gnome with the shell extension "Dash to Panel" (and also in Windows 10 panel). They both behave as I think also Latte should handle this, when you have both "Preview and Highlight" selected in the settings.
