feedback effect gets slow when resizing window #7

Closed marioecg closed 1 year ago

marioecg commented 1 year ago

I noticed that when you resize the window for a while the canvas starts to get a bit jittery and slow, specially for the ping-pong buffers. Do you know why?

I'm testing on a 14" M1 Macbook Pro

It seems to affect all of what's rendered, not just the ping-pong outputs.

My bad, I was re-triggering draw() in the example and doubling the amount of draw calls every time. https://github.com/patriciogonzalezvivo/glsl-sandbox/commit/5d26de82f360bcf0de789fbb55a654e380aee127
