PDFs cannot be scrolled by touch, and "jump" back and forth between the "current" and "new" scroll positions when scrolled by mouse

Project Member Reported by w...@chromium.org, Jun 9 2016

Issue description

Version: 52.0.2743.19
OS: Chrome

What steps will reproduce the problem?
(1) Load a PDF - the one I'm looking at is someone's resume; not sure how they created it.
(2) Try to scroll it by touching the screen (on a touch-screen device...)
(3) Try to scroll it using the mouse on the right-hand-side scroll-bar.

What is the expected output?

Expect that touch scrolling works, or at least that mouse scrolling works smoothly.

What do you see instead?

Touch scrolling does not work at all.

Using the mouse to drag the right-hand-side scrollbar the scroll position keeps jumping back and forth between wherever the mouse is, and the original scroll position.

FWIW still repros in 52.0.2743.32.

The PDF plugin actually crashes in response to attempts to touch-scroll, it seems.
I saw  bug 617021  go by and that got merged with  bug 615512 . Same problem?

The slow scrolling is probably  crbug.com/619117 . If there is a crash then please share more details - a repro, and crash ID if possible.

 Issue 620174  has been merged into this issue.
This completely breaks mousewheel scrolling for PDFs as well.

Google Chrome	52.0.2743.32 (Official Build) beta (64-bit)
Platform	8350.21.1 (Official Build) beta-channel samus
Comparing apples and oranges, but PDF scrolling with the mouse wheel on Linux with Chrome 53.0.2767.4 works fine for me.

Chrome 52.0.2743.41 on ChromeOS feels a bit laggy when touch pad scrolling, but I haven't been able to get it to crash.
dnschneid: Mousewheel scrolling on the Chromebook feels ok. If it's broken for you, can you indicate if it's for a specific document or with all PDFs? I tested with the PDF 1.7 spec doc.
It's happened for all PDFs I've tried.  The mousewheel doesn't move the page at all.
I'm seeing the same behavior.

I'm no longer able to repro this on my Flip device, at 53.0.2768.0.

If this is fixed in 53, can we find and merge the changes into 52?
52.0.2743.41 is the latest version of Chrome for ChromeOS on the beta channel. Have you tried updating to see if that has the fix?

Re #13: Both of my touch-screen devices are now on dev-channel; sorry. :-/
That's ok, we still got 2 other people on this bug on beta channel. Plus you said it's working properly on M53 now.
52.0.2743.32 still seems to be the latest available for Samus.  I'll let you know when it updates if things work any better.
OK, just got an update:

Google Chrome	52.0.2743.49 (Official Build) beta (64-bit)
Platform	8350.38.0 (Official Build) beta-channel samus

...and all the scrolling issues appear to have been resolved.  Mouse wheel, two-finger scroll, and thumb drag all seem to work properly again.

As dnschneid@ confirmed that it is fixed. And I also verified no problem on the latest Chrome OS:
Chrome: 54.0.2840.43 Beta (64 bit)

I am closing it now, feel free to reopen it if you still see the problem.
