Hello to everybody,
I have an application that show video images but sometimes stop paint frames.
After experienced this problem I did some debug with spy++ and found that windows messages don't come to my window therefore it doesn't repaint, unless I go with mousepointer on the window and in this case messages come.
This behaviour happen on exe release and debug also.
System is intel i7 8 cores and cpu is not really loaded 50-60% max, sometimes less and I have the feel that the problem is not correlated to the cpu because sometimes I've seen the problem happen just with 15% cpu load.
Did anyone experience problem like this and have any idea how can I face it?
ADDED INFO AND QUESTION
I need receive WM_PAINT message regularly, how can I force to regularly retrieve this message from the queue?
