I spent a while trying to find repro steps for this issue, since I still run into it occasionally, but I've never managed to find anything remotely reliable. In particular, I was never able to reproduce it on a fresh instance of FF - for me it only happens after the process has been alive for a while. Not sure if that means anything.
Would it be possible to add some instrumentation that would let us dive into this issue once we reproduce it - like a hotkey or toolbar button that would start logging painting and invalidation? When I hit this bug it is usually fairly persistent - i.e. all drag-selection operations on a webpage show the same extremely long delay - so if there was instrumentation like that, I'd be able to use it to record info on the bug the next time I see it. -kg On Tue, Dec 18, 2012 at 3:02 AM, Robert O'Callahan <rob...@ocallahan.org> wrote: > Bug 808466 is about changes in selection sometimes not being rendered in a > timely manner.
