You can generate a number of images using a few threads when the flag is 
on then switch it off and compares results. The test should not draw 
different(on/off) modes in parallel but it can draw the images for the 
same mode.

Note that the test can be run on some slow/virtual systems, it would be 
good to have some additional time.
