[1.1.9.28] browser renders blurry while scrolling [answered]

Hi, thanks for the explanation. Does this feature also apply for the following scenario?:

• enter a URL
• wait for the content to be displayed (no blur)
• scroll down (see blurred content)
• wait until content is readable
• scroll back to content that had already been loaded and rendered without blur - and observe that that content is now blurry again
• wait for the content to be readable again.

I was quite surprised to see that previously loaded content has to be rendered again - especially since I think this was not the case in earlier versions. At the moment I cannot test it using an older version of Sailfish, because I only have one phone =)

Well, this is not ideal, but not unexpected. Gecko v31 seems to still have some problems where it can trigger full screen repaints even when nothing animated is actually visible on the screen. If you're interested nglayout.debug.paint_flashing pref can be used to show paint invalidations. The situation does seem to be a lot better in gecko v38. We're currently in the process of upgrading to it, but it'll take some time until the migration is done. If the feature bothers you too much you can disable it by setting layers.low-precision-buffer gecko pref to false.
