Status: RESOLVED INCOMPLETE

(Core :: Graphics: WebRender, defect, P3)

Description

[u672847]

Attachment: An example of a black box.

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:82.0) Gecko/20100101 Firefox/82.0

Steps to reproduce:

Scrolling or switching between tabs with webrender and hardware acceleration enabled.

Actual results:

Produces a black box on a random portion of the screen. Particularly the upper and bottom corners, but sometimes random sections in the middle. Disabling webrender makes the boxes appear with less frequency, but they still show up from time to time.

Expected results:

Ideally, the boxes shouldn't be showing up at all.

I apologize for neglecting to do that in the first place; slipped my mind.

Kote, can you try updating your graphics driver?

Windows seems to determine that my display drivers are already up-to-date.

Jim has this device, let's try to get a similar driver.

Comment 11

[Jeff Muizelaar [:jrmuizel]]

Kote, do you still see this if you set gfx.webrender.compositor=false in about:support and restart?

Comment 12

[u672847]

Doing that now. Due to the sporadic nature of the problem, I'll report whether it worked or not in a day.

Comment 13

[u672847]

Sorry, I clearly let the time get away from me (been a rather hectic week). That said, this actually did in fact solve the problem. Haven't had a black box this whole time.

Jim has this device, let's try to get a similar driver.

I have been testing on a
Lenovo Yoga 920
UHD Graphics 620

with two different drivers -
27.20.100.8681 (2020)
23.20.16.4849 (10/2017)

So far no luck reproducing. I was not able to get the exact driver version installed, but it's within one month of the driver reported here.
Driver Version: 22.20.16.4785
Driver Date: 8-29-2017

Potentially the same root cause as the nvidia flicker bug, something to do with direct composition.

Comment 16

[Jeff Muizelaar [:jrmuizel]]

I'll see if I can summarize some of the other reports.

Kote, can you try using this driver? https://downloadcenter.intel.com/download/30148/Intel-Graphics-Windows-10-DCH-Drivers

Comment 18

[u672847]

I set gfx.webrender.compositor back to true and will now test to see if the driver alone keeps the black boxes at bay. Will try to report back in a couple days again.

Comment 19

[u672847]

... Never mind, apparently this driver isn't validated for my computer.
