Revert previous workaround and fix it in a more correct way in Sonic-Win and Sonic-Workspace by not updating by every single frame but instead update per 50ms

+Subject: [PATCH] Batch strut-triggered workspace rearranges to reduce stutter
+
+When a panel animates between floating and docked states it can change
+its strut several times in quick succession. KWin handled those by
+calling Workspace::rearrange() immediately, which recalculates work areas
+and calls checkWorkspacePosition() on every client. That O(n) work on
+every strut update causes visible stutter on X11 when other animations
+are running.
+
+Use the existing scheduleRearrange() path instead and bump its timer
+from 0 ms to 50 ms so rapid strut changes are coalesced into a single
+re-layout. This keeps the work area correct while reducing the amount
+of synchronous work done during panel transitions.
