Thanks for the quick response (and all your excellent responses thus far).

I noticed the clipping that occurs with Qt but was focusing my work on
OpenGL since the results are much...prettier.

Will this be addressed in time for 0.22 or will it require a larger OpenGL
fix upstream? Is there a workaround to not use negative offsets on the menus
where this behavior occurs?


PS. Are you experiencing this as well? Can it be fixed with an upgrade of
hardware or other configuration possibly?
