Your MP4 video doesn't work, can you attach it to this bug, please.

On a clean profile is the same. Video attached in first post (please use "Save as", not "Open", otherwise Firefox will show error). In the video a bit exaggerated. The reality is much less and less frequently, BUT nonetheless has a strobe! It should not be. And it's annoying.

Do File I/O(HDD access) happen during scroll?

No. I think it's maybe because of system timer. I found a similar discussion on the Russian http://forum.mozilla-russia.org/viewtopic.php?id=57622

In Opera 12 is always smooth scrolling, for example.

Please recheck this problem. I really like Firefox, and I see it as a transition from the Opera. But jerks scroll spoil everything. I already tried extensions "SmoothWheel" and "Yet Another Smooth Scrolling", but there too jerks (strobe) :(

Does the problem happen if you start Firefox in Safe Mode? See http://support.mozilla.com/en-US/kb/Safe+Mode

How are things going with the correction? Need more information?

Comment 13

[Denis]

I checked on Linux Mint Cinnamon x86 and there was very smoothly, without strobe. Better than on Windows.

Try to update your GPU drivers, they are outdated.

[Denis]

I update from http://www.intel.com/p/en_US/support/detect?iid=dc_iduu to 9.17.10.3223
It did not help.
