pronvit: Your uninstall instructions worked for me (although I also removed engine-chooser since your new package includes it). I don't know if this is the case all the time, but I had to reboot before I could use webkit in the browser.

After rebooting, everything looks very nice! Finger scrolling works everywhere now, scrollbars are back for quick scrolling. The only reason I know I am using webkit currently is the high acid3 score, and the fact that downloads still aren't working.

Very nice work!
