* there is no problem on windows 7 home premium system at home.
  I don't know what makes this difference.
  2 different video adapters(problem on intel on-board, no problem on nvidia PCI-ex)?
  But on windows vista, intel on-board display has no problem.
* these windows 7 home premium systems upadated regularly via windows update.

Does windowed rendering behave correctly on the Windows 7 machine? Are your 
video device drivers up to date? You can also try running with the 
`--disable-gpu --disable-gpu-compositing` command-line flags.

* windwoed rendering runs always ok(on all os evrsions, with or without 
off-screen)!
* latest driver was installed(Intel HD Graphics 2500 v10.18.10.3958 via 
intel.com)
* If both or one of these 2 options( --disable-gpu --disable-gpu-compositing) 
supplied, then behave little differently...
  - new black unfilled area is painted correctly...
  - but no animation occurrs, still same problem!

Thank you for the response.
