Windows 8.1 no update when in background. WM_PAINT ignored?

Hi,

when my app is running and it is under heavy load and it runs in the background, sometimes there is no rendering. The screen does not get a refresh. It looks like the paint message is ignored. To turn on the rendering again, the window must be klicked upon, bringing it to the foreground. Any ideas what the causes could be?

Hardware is Nvidia mobile OS is Windows 8.1

Best,
Henniman
