Created attachment 454460 [details] screenshot We should probably set a min window width to prevent this, or hide the fx button when the width decreases below the width of the captions and button.
The Windows UX guidelines mentioned somewhere that if a window becomes too small, the entire chrome should disappear. This happens on the MS Office programs.

In Windows 7, explorer has a min window width, and MS Word 2010's icon slightly overlaps the minimize button. http://img707.imageshack.us/img707/1237/clipboard01jur.png
This issue doesn't belongs to commpressed windows only. It appears also sometimes in the normal workflow without resizing the window. The personas theme overlaps then the caption buttons. There is no way to resolve this behavior except to close the window it belongs. There must be a case where the window painting function first draw the window frame and and then the personas theme, so the theme overlaps the buttons. If I switch between the firefox windows the issued window is first correctly drawn. But if I move the mouse in this window the personas theme overlaps the buttons again. Tested with: Firefox 4.0b5

Do you run in aero basic, or has your aero glass been shut down on the window? (The fact that you're messing with java in your two tabs seems suspect.) If you're experiencing aero glass shutdown (bug 545892) and have a way to reproduce that, please post it in that bug.
the minimum window size bug is bug 548777
This is due to the flex spacer in the middle having a minimum size. Which from my understanding shouldn't happen but something is clearly forcing it stop flexing at a certain point.
The Firefox button is going to be removed in bug 863753.
