Pager drag'n'drop glitches

SUMMARY

Drag&Drop in Pager applet is very glitchy on multi-screen setup.

STEPS TO REPRODUCE
1. Connect two monitors, extend to any side.
2. Open some windows, add Pager applet to any containment if you didn't have one.
3. In the Pager applet, drag any window's outline around.

OBSERVED RESULT

For a brief period of time, the outline that represents a window jumps back and forth between a drag position and original position. Then it proceeds being dragged as normal.

EXPECTED RESULT

Drag & Drop should be smooth.
