This appears to happen on any page that scrolls (e.g. I just saw this on Google search results, YouTube pages, and this simple page http://seventransistorlabs.com/ClassD1/index.html). Happens at least when scrolling with the scroll wheel, I haven't tested with other scroll inputs. Tested without extensions.

Unable to repro this issue on Ubuntu Trusty (14.04) for Google Chrome Stable Version - 51.0.2704.79

Screen-recording is attached.

@pavlina.chris: Could you please re-test the same on a clean profile [chrome://settings -> Add Person] and let us know your observations, which would help us in triaging it further.

Also, update your Google Chrome to Latest Stable Version - 51.0.2704.79

Thank you.

I've had this same bug for several months now.

Currently running 51.0.2704.79 (64-bit)

OS: Elementary OS Freya 0.3.2

I have tried starting with a new profile, and no addons, no changes.

It happens exactly as issue writer said, the page foreground starts to flicker, usually disappears and only background is left. I have noticed that it resets when I hover over the scroll bar, and it randomly puts the scroll to the top or bottom of the website.

I can't really find any specific situation where this happens, but as said before, pretty much on every page that has scroll this happens.

I am also running Chrome with --force-device-scale-factor=1.5

I was wondering if it's a driver issue with my graphics card, I am running this on a Thinkpad E540 which has integrated Intel card and Nvidia Geforce GT 740M (using the Intel one)

Here is a video of I took it happening on theverge.com, please skip to around 1:20

@rnimmagadda - I'll test later today, won't have a chance for a while.

@kristian... - your video looks exactly like what I see. I have a similar graphics setup to you, so perhaps that's it. This is an Asus N56VM with dual graphics and I am also using the Intel graphics by default:

00:02.0 VGA compatible controller: Intel Corporation 3rd Gen Core processor Graphics Controller (rev 09)
01:00.0 VGA compatible controller: NVIDIA Corporation GF108M [GeForce GT 630M] (rev a1)

Haven't had the issue for months though.

@rnimmagadda - on second thought, I do have time to test now, and just did. Latest Chromium, 51.0.2704.79 as requested, new profile, still happening.

@rnimmagadda - I should also add, since I didn't notice you had attached a recording before, that it takes me more scrolling than that to trigger the bug, so the recording isn't quite conclusive yet. I went up and down continuously on that page for about 30-45 seconds when I did your new-profile test a few minutes ago, before it finally glitched out.

Thank you for providing more feedback. Adding requester "rnimmagadda@chromium.org" for another review and adding "Needs-Review" label for tracking.

I have done the scrolling more than 1 minute, but the video recording size is huge which cannot be attached here.

It looks like this is specific to your Configuration [Asus N56VM with dual graphics]. Could you please perform the steps mentioned beneath and let us know your observations.

1. Uninstall your Chrome.
2. Remove this folder -> Home -> Control+H -> .config -> Chrome-Stable
3. Install the Google Chrome Stable Version - 51.0.2704.79
4. Re-test the same on a clean profile [chrome://settings -> Add Person]

Thank you.

 Issue 617485  has been merged into this issue.

 Issue 617778  has been merged into this issue.

I do not have any flickering issues, but I experience scrolling issues as I outlined in https://bugs.chromium.org/p/chromium/issues/detail?id=617485.

The two may or may not be related.

I'm seeing this issue on multiple machines:
* HP Z440 with NVIDIA Quadro K620, NVIDIA driver 340.96 and Ubuntu 14.04 (kernel 3.19; X11 1.15.2; mesa 10.1.3)
* HP Z440 with NVIDIA Quadro K620, NVIDIA driver 340.96 and Ubuntu 14.04 (kernel 4.2; X11 1.17.2; mesa 11.0.2; aka. Wily HWE stack)
* Lenovo X250 with Intel graphics and Ubuntu 14.04 (kernel 4.2; X11 1.17.2; mesa 11.0.2; aka. Wily HWE stack)
* Lenovo X1 Carbon gen. 4 with Intel graphics and Ubuntu 14.04 (kernel 4.2; X11 1.17.2; mesa 11.0.2; aka. Wily HWE stack)

I can reproduce the issue by opening the attached svg file, use varying zoom levels (25%, 200%, ..) and then scroll up and down. After a while the page goes blank/white, the scrollbars vanish and once Chrome recovers I'm back at the beginning of the page. Sometimes I get flickering and whatever misbehaves seems to be repeatedly misbehaving in this case. Sometimes Chrome doesn't recover at all and I have to reload the page.

@rnimmagadda - okay, performed steps exactly as you described. New Chrome install (Google Chrome this time rather than Chromium), 51.0.2704.79; new .config subdir; new profile - confirmed, problem still occurs.

Could this be related? https://bugs.chromium.org/p/chromium/issues/detail?id=606152

This is certainly not a duplicate of bug 606152. Bug 606152 is only about flickering and that goes reportedly away if a window is unmaximized.

This bug is about flickering/flashing AND resetting the page position to the top.

Workaround:
This issue goes away for me if I disable Smooth Scrolling under chrome://flags/.

Can confirm comment 18, disabled smooth scrolling and no flickering has occured in the past couple of hours.

I can also confirm this goes away with smooth scrolling disabled.

Disabling smooth scrolling in chrome://flags/ does not fix the scrolling issue outlined here and in https://bugs.chromium.org/p/chromium/issues/detail?id=617485.

@bokan: Could you please let us know if this issue is related to - 609748

I don't think that  bug 609748  and this bug are related.

First of all I have seen  bug 609748  only on laptops with multiple input devices (touchpad, trackpoint, mouse, ...). This bug also happens on desktop machines with a single input device (e.g. mouse).

Secondly this bug can be worked around by disabling smooth scrolling. This workaround doesn't work for  bug 609748 .

Agree with #24, this seems unrelated as  issue 609748  doesn't have any flashing/graphical glitching.

+skobes@/ymalik@ since disabling smooth scrolling supposedly fixes this

I can't repro this using an external mouse on my desktop and the touchpad on my lenovo thinkpad. I tried using on theverge.com and google images. 

Is there a more deterministic repro for this?

@ymalik: I can easily reproduce it with the SVG attached to comment #12. 

I gave this another test run on stable (51.0.2704.103), beta (52.0.2743.41) and unstable (53.0.2767.4). On all versions I've used Switch person followed by Browse as Guest and then I've opened the SVG from comment #12 from local storage.

On stable I could reproduce the flashing and reset of the scrollbars to the upper left corner within a minute as described in this bug. On beta and unstable I had a harder time reproducing the issue as the flashing issue is mostly gone. If it flashes then it only flashes for a brief moment. On beta and unstable I also saw the reset while scrolling but the reset was harder to trigger and it was different as it reset the scrollbars to the lower right corner.

@ymalik: With which version did you try to reproduce the issue?

I can't repro this but it smells like a gpu or driver issue.  Smooth scrolling draws more frames which would explain the correlation if there is some kind of resource exhaustion happening.  Does it work if you disable hardware acceleration in settings?

I've seen both this issue and the one in the merged ticket here:
https://bugs.chromium.org/p/chromium/issues/detail?id=606152

Are those the same issue?

Bug 606152 appears to be a problem with how Chrome interacts with SNA in the intel driver (the workaround of moving to UXA seems to fix things) but this one remains.

Closing as obsolete / not reproducible.
