Fix position:fixed by adding transform:translateZ(0) to element. For smooth scrolling with 60fps.
This extension optimizes scrolling performance by adding transform:translateZ(0) to layers with position:fixed. this triggers hardware-acceleration and makes scrolling more fluid.
in the options page you can turn features on and off and decide if you prefer speed or effects.
I also managed to apply this trick to the real chromium.app, so you can try it as a "native" chrome feature without the extension. for the brave ones here is a beta to download from my dropbox: (its latest chromium compiled with the patch). https://www.dropbox.com/s/cesnf1ekte8kwmn/Chromium.app.zip?dl=0
The screenshots show the difference of the extension in action. See comments in the adressbar of the screenshots.
a) unoptimised, lot of green repaint areas, b) with extension enabled, still scrollbar is green. c) alternative with patched chromium.app where scrollbar is hidden, and no green repaints at all.
I try to commit the patch (actually only 2 Lines of Code) to the official chromium git, but it might take a while to get access and get it approved. but in some weeks it might be part of normal chrome.app, so everybody can benefit from better scrolling experience.
the code of this extension is also available on github:
v0.3: performance improvements + bugfixes.
v0.4: fixed typo in comments
v0.5: code cleanup and bugfixes, hopefully last version for today ;)
v0.6: cleanup , optimizations
v0.7: code optimization
v0.8: implemented icon + badge-number for improved divs, also new options-page
v0.9: optimized default setting.
v1.0: reading css directly now and patching css. much more efficient and less false detect.
v1.1: bugfixes, better parsing of css, respecting media-queries, reapplying transforms to reduce false positives.
v1.2: bugfixes for subpixel-antializing. translateZ(0) forces grayscale antializing, so the css is now only applied during scrolling and removed when scrolling is finished. (during reading).
v1.4: improved, option to turn off antializing fix which is faster, option for delay of antilizefix in milliseconds. (see options)
This extension also works great in combination with "SmoothScroll" Extension: https://chrome.google.com/webstore/detail/smoothscroll/nbokbjkabcmbfdlbddjidfmibcpneigj
Please rate the extension and give feedback und bug-reports, this helps me to improve the extension.
