      Description

      DosBox 0.74.2 from rapps.
      0.4.11-RC-30-g83e4a61 affected
      and everything down to at least
      SVN r72748 is affected as well.
      I know the issue since long time, unfortunately mentioned it just as a remaining thing in historic CORE-11245. Imho it deserves its own ticket.

      VBox4.3.12 + VBEMP + inbuilt Mesa

      Reproduction steps
      -set desktop resolution to 800x600 32bpp
      -start DosBox main app (it will start windowed by default)
      -Hit Alt+Enter, it will properly switch to fullscreen (side-note: leaving the taskbar visible)
      -Release the Alt-Key (yes that's also necessary on Windows)
      -Hit Alt+Enter again

      Expected result
      It returns into windowed mode, and continues to draw content
      Like Windows XP SP3 does. xpsp3_ok.webm

      Observed result
      It returns into windowed mode, but stops drawing anything into the window.
      0.4.11-RC-30-g83e4a61__dosbox.webm
      0.4.11-RC-30-g83e4a61__dosbox.log

      (Even minimizing/maximizing or moving the window offscreen will not fix it).
