1679592 - Hardware acceleration problem (Windows 7 / 1920x1080@144Hz) Nvidia 1660 GTX

Status: NEW

(Core :: Graphics, defect, P3)

Description

[master-chan]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

I launch and try to use firefox.

Actual results:

Performance of page scrolling is horrendous, because firefox seems to not use hardware acceleration by itself. RAM and CPU usage are normal. GPU usage is almost 0. Safe mode doesn't fix this problem. Problem persists with whatever number of opened tabs, even one.

Problem can be temporarily (about 10-15 seconds) fixed by tabbing out and in firefox window (Windows 7, Aero enabled), but then performance drops back. Also problem doesn't exist if there is any 3D application working in background.

Expected results:

Firefox should properly use hardware acceleration.

It auto-posted with broken markdown but it should be the info you requested.

WR is enabled here. The user has some interesting gfx errors that might be worth looking at.

Might be fixed in 84, related to bad glass calculations.
