Hi ssvb & hglm.
Thanks for all your hard work
I've installed your driver on a standard install of Raspbian and can definitely see a speed improvement, especially to dragging windows around. I was one of the people who was testing Simons Accelerated X driver, so I've reproduced some of the scenarios that produced problems for his driver to see if yours was ok and it is fine
The only very minor thing I've found so far is if I load a large (2300x1800) image into the standard 'image viewer' that comes with Raspbian and tell it to display 'original size' the window will only show the top left corner of the image, it doesn't matter where you drag the sliders to, you will only get the top left corner, if you increase or decrease the image size using the '+' or '-' buttons, ie to 95% or 105% it works perfectly, it only seems to affect it at 100%. I haven't been able to go back to the original driver yet to check that it isn't a problem with 'image viewer' itself, I'll report back.
it does it with the old X driver as well
I've been doing more playing and it definitely improves all the browsers I've tried ('Web', Chromium, Midori) they all scroll smoother/faster, especially if there are lots of images, like say an Ebay page.
Thanks again for all your excellent work on this driver, do you think any of your 'low hanging fruits' from your round up will also get incorporated, to make it even better.
