Created attachment 3537 Fix-work-with-grouped-windows.patch To reproduce: 1. In tasklist preferences dialog set "Window grouping" -> "Always". 2. Open several windows of the same application (Terminal in my case). 3. Try to select one in popup menu. This is the regression since 4.8.1 introduced by commit a0a3d318c8d688f505f4fefe2ce81c0fc48b5cef ("Activate windows on button release events (bug #7296)."). Attached patch solves the issue for me.
Already fixed in master.
