1197546 - Black border artifacts around transparent layers

Status: RESOLVED WORKSFORME

(Core :: Graphics, defect)

Description

[Katelyn Gadd (:kael)]

Attachment: Slate header

Recently it seems like transparent/semi-transparent layers have had thin black borders around them - some sort of sampling or compositing artifact. The same pages look fine in IE Edge on this machine and I remember this working correctly before.

The place most people would see this is Youtube - there's an edge artifact above the controls when they're visible. But it also happens on Slate below the top header (see URL for one example), and I've seen it elsewhere.

Running GeForce 980TI on Windows 10 x64, latest NVidia drivers.

Attachment: Normal youtube video for comparison

Comment 2

[Katelyn Gadd (:kael)]

Attachment: controls visible.png

Compare this with 'normal youtube video for comparison', you'll see a horizontal black artifact a bit above the video controls.

Comment 3

[Katelyn Gadd (:kael)]

If I set 'gfx.direct2d.disabled' the bug no longer reproduces.

Comment 4

[Katelyn Gadd (:kael)]

This also reproduces on my laptop, about:support follows:

Comment 5

[Ryan VanderMeulen [:RyanVM]]

I'm not seeing any lines on Win10 with a current nightly build or with Fx42b4. Can you still reproduce?

Comment 6

[Katelyn Gadd (:kael)]

Still reproduces with the top header in the slate URL provided in the bug. 43.0a2 (2015-10-06), Win10x64, Geforce 980ti, 4K monitor

Comment 7

[Ryan VanderMeulen [:RyanVM]]

I wonder if it's a high-DPI issue. My monitors run at 1920x1200.

Any chance you'd be willing to try bisecting this with the mozregression tool? Information on it is available at http://mozilla.github.io/mozregression/ and a command like |mozregression --good-release 41| should work (assuming this used to work OK for you with Fx41, that is).

Comment 8

[Katelyn Gadd (:kael)]

I've had significant problems every time I've tried using mozregression in the last few months. I'll see if maybe it will work right on my laptop.

Both of my machines (laptop, desktop) are HiDPI so I suspect DPI is the problem here. I don't have a low-DPI panel to attach to either of these, but I'll see if I can get FF to start in a mode approximating normal DPI with 100% zoom and maybe it will go away.

Comment 9

[Ryan VanderMeulen [:RyanVM]]

Thanks!

Comment 10

[u279076]

Hi :kael, it's been about a month. Do you have any update here?

Comment 11

[Katelyn Gadd (:kael)]

No update. URL in the bug report still reproduces on all my HiDPI machines (Win10 desktop, Lenovo Yoga 2, Surface Book)

Comment 12

[u279076]

Can you please double check that you're running the latest drivers and any other OS/firmware updates?

Comment 13

[Katelyn Gadd (:kael)]

Latest drivers on all 3 devices. Windows 10. Different GPU setups (NVidia GTX 970Ti, integrated Intel, integrated intel/NVidia optimus setup)

Can you please provide an updated copy of about:support so we're working with current information?

[Katelyn Gadd (:kael)]

The youtube artifacts don't reproduce anymore, and it's actually possible to reproduce the Slate artifact in Google Chrome on high-DPI now. So I think this bug may be fixed and Slate's busted layout just happens to resemble it. I'll keep an eye out to see if this bug is totally gone.

kael, do you have an update? If you haven't reproduced this recently then let's close this bug as worksforme.

I haven't seen this on any of my devices in a while, so I think it's fixed. Thanks.
