WFM in Fx45b4 and all of earlier Firefox on Win10. This should not happen so long and there is no reports.

Actually, let's leave this as [New] since we managed to replicate it on several test environments. Please check the [Affected platforms] & [Affected versions] sections from the bug report in the future.

Well, I understand the flickers now, it is due to a layout update (panel resize) and once only after per-click. Anyway, I think this bug is a "trivial" problem. I has checked them before modifying, changes was in order to a double check.

Seems like we should avoid the intermediate state painting here, which smells like a XUL/layout/graphics issue to me.
