The "speedup patches" for alpha-blended images that have gone into 3.5 tree have caused awful regressions there. if its nvidia, then its unfortunately a wontfix. nvidia has changed their driver to make firefox faster, and they will not re-add acceleration for "qt3's weird ways of abusing xrender". Unfortunately a proper fix requires someone familiar with qt and X and Xrender; and thats not me. Unfortunately qt4 did not fix this issue, so in the long term we'll have to work around Qt and add direct xrender handling in KHTML. > Is it known problem? What is causing this? Is there any workaround? revert r502582 and try again. Dirk
