Most of time everything goes well. But sometimes video disappears on my window and I see (via ProcessExplorer) GDI handles leaking.
GDI handles count increase for about 10000 and after that it's impossible to create any more window for application.
When handles count just began to increase I tried to access my process via gdb and see following messages:
