Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Steps to reproduce:

I've opened a RAD PDF that has more than 1 page (ex.: https://modzillatest.medfarsolutions.com/RadPdf/View/3) with Firefox v43.0.3 (and I've also seen the bug in 43.0.1, 43.0.2 and 43.0.4). I've ticked some checkboxes. Then I scrolled down using the scrollbar completely on the right (not the inner scrollbar). 

Note: I've tried locating the version where the bug started to appear with moz-regression, but all versions seemed correct there. AFAIK, I was using the same configuration (in Options).

Note: The bug also sometimes appears on RAD PDF's of only 1 page (ex.: https://modzillatest.medfarsolutions.com/RadPdf/View/1).


Actual results:

The checkboxes appeared unticked (as soon as I started scrolling down. When I scrolled up again, then they reappeared).

But when I checked in the console window, the ticked checkboxes became visible again. And when I printed the RAD PDF, the checkboxes also appeared ticked.


Expected results:

 The checkboxes should have remained ticked when I scrolled down.

I works fine in FF44+, so it's probably already fixed.

Could you download Beta and confirm it's fixed on your machines, please.

I've been unable to reproduce on WinXP, Win7, Win10, or Ubuntu 15.10 so far. Based on the screencast, it looks like some kind of graphics issue, though.

Mathieu, can please attach the contents of your about:support section to the bug? Unfortunately, these kinds of problems can be highly configuration-specific :(. Thanks!
