View Full Version : Resize OpenGL Window lags

07-25-2013, 05:06 AM

I have a simple example that only clears and swaps.

If I resize the window with the mouse I see a "gap" on the right and/or bottom. If I resize the window really fast then the gap will be bigger.

How can I remove this effect?

setup: intel hd3000, windows 8

Make sure you app is not servicing window erase background events - eg an mfc app will do this by default.
