SUMMARY

Submenu items of plasma global menu are displayed corrupted or in wrong scale. I have seen this does not occur for a specific item with submenu after the submenu list is displayed once.

STEPS TO REPRODUCE
1. Have globalmenu widget enabled. open any application with app menu (most kde app).
2. Hover over a menu dropdown item  and reveal the submenu list.
3. Hover over same item again after closing the menu.

OBSERVED RESULT

Submenu list renders with magnified fonts, sometimes corrupted.

EXPECTED RESULT

List should render normal.

This doesn't seem to happen with X11, so I believe it's a KWin bug

I doubt that. I've not seen it with menus in any other app nor with 
plasma popup menus.
