I'm creating a visualization where I'm drawing a lot of 2D lines. It runs nicely in 60fps with the default blend mode, but when I try to use some slower blend mode (ie. screen or add), the screen turns grey. If I lower the frame rate to around 10-20fps, it works again nicely.
I'm using version
2.0b8. Do you have any idea why whole screen turns gray when my drawing algorithm can't keep up to the speed of 60fps? Shouldn't it just start dropping frames if I'm not drawing fast enough?
