Ribbon area is sporadically white

Hi Tobias,

I know we have seen some issues in the past with remote desktop scenarios where on resume a new template was assigned by WPF but some element that was tracked internally from the original template was still being referenced and used, which could lead to some UI glitches.  As far as we know though, any instances of that kind of thing have been worked out by now and we're not aware of any issues in the current version related to remote desktop usage.

Many years back we also had seen some odd instance that occurred infrequently but randomly, where a Window's background wouldn't initially paint, although some child controls would.  I believe that was due to something with WindowChrome that might have inadvertently triggered some bug with graphics cards.  However we have refactored WindowChrome since then and haven't seen that happen in years now.  It might have been our refactoring or a driver update by graphics card vendors that resolved it.

To sum up, we're not aware of any issues like what you describe in the most recent versions, so hopefully doing the upgrade will resolve it for them.
