When I run the first program with a window shown in the stasks bar, it shows its icon on the right side rather than the left side. Dragging it to the left results in plasma-desktop crashing.
Stasks settings: grouping by program name, manual sorting, no expanding.
Steps to Reproduce:
Start with stasks empty, then run something (e.g. kwrite). The icon appears on the right. Drag it to the left and see the panel and desktop disappear and (usually) get recreated, with the icon still on the right side of the stasks bar.
Workaround: open another window (the icon goes on the left side), then drag the first icon to the left.
Hmm, this is strictly upstream bug, nothing gentoo can do about (could you please please report this thing upstream and add url to upstrem bug to URL field above?)
Well, upstream seems to be dead, and the replacement is apparently smooth-tasks, which doesn't compile (see bug 352404)
