[Qt-interest] QMenu OpenGL bug, Windows 7 x64, Quadro 4000, Qt 4.5.3

[Paul Miller]

Anyone seen this? I have a user running Windows 7 x64, a new Quadro 4000 
graphics card with the latest drivers, and he is running my Qt 4.5.3 (64 
bit app) and having a weird refresh problem I've never heard of.

In the app there is a GL widget, and in some cases right-clicking in the 
widget pops up a QMenu (popup) using QMenu->exec(). In his case, when 
the menu goes away, only the area under the popup can then be refreshed. 
He can jar it back into action by opening one of the main menubar menus, 
but it always happens when popping up this popup menu over the widget.

Ring any bells for anyone?
