Hi.
I'm still using Squeak 2.0. I was doing something with function plotters and I wanted to make alpha-blending while drawing. My video card is set up at a bitdepth of 16, and so was the image. But I had to make the image bitdepth 32 for alpha blending to work. Correspondingly, the image size went up by over 4mb. But the video card was still set up at a bitdepth of 16, so bitmap bitdepth crunching was being performed somewhere. After I finished the thing, and noticing that display speed was much slower (maybe due to such bitdepth crunching), I closed the morph worlds and set the display depth back to 16. But the image never got smaller, and the screen updating did not recover its original speed. I tried a bitdepth of 8, but the image didn't recover its original size.
Where should I take a look to see what's going on?
Andres.
