Missing tiles with external monitor connected to Macbook Pro

Project Member Reported by juberti@chromium.org, Apr 25 2017

Issue description

Chrome Version:  58.0.3029.81 (64-bit)
OS: 10.12.4

What steps will reproduce the problem?
(1) open gmail.com
(2) drag window to ~full screen
(3) scroll (not always needed)

What is the expected result?
Gmail is displayed correctly. On my previous MBP (mid-2013), this worked fine. On my new 2016 MBP, I encounter display glitches.

What happens instead?
Gray boxes appear over top of Gmail, and controls randomly flicker and vanish.

The about:gpu report indicates some bad things are happening.

Not sure this is a dup, since this bug occurs on Mac as opposed to Windows. Is this a cross-platform issue?

Oops I edited the wrong bug, sorry about the confusion. 

This looks like GPU process has hung and not recovered, possibly during resizing?
Cc: dbrownlee@google.com
Yes, looks like the GPU process is hanging frequently, and when that happens (and I assume software fallback occurs), I start to see the aforementioned problems.

When you say resizing, do you mean window resizing?
Also, in working with techstop on this, once the GPU process crashes, the problem can be reproduced on the internal display.

If you just disable hardware accel do the problems reproduce? That'd be easier to debug.
The problems still occur if I disable HW accel in Chrome prefs.
It almost seems like the problem is in the SW mode, since I don't see the problem when HW accel is active.
Right, so if you disable hardware accel, what's the minimum set of things you need to repro. Do you need an external monitor?
I just reproduced it via the following steps:

0) Disable HW accel in Chrome Canary prefs
1) Attach external monitor
2) Relaunch Chrome Canary and make full width/height
3) Open gmail.com
4) See problem

I can intermittently reproduce it with the same steps, minus the external display. Usually I have to perform some other step that seems to tax the renderer - one common one is to view a lengthy PDF in Chrome, where I commonly see missing 512x512 (approximately) blocks. Sometimes they eventually fill in, sometimes they don't.

Any idea why the GPU process is crashing?
