Status: RESOLVED DUPLICATE of bug 1870488

(Core :: Graphics: Canvas2D, defect)

Description

[Mayank Bansal]

Open the testcase from bug 1870488 (https://bug1870488.bmoattachments.org/attachment.cgi?id=9369102)

AR:

The VRAM quickly starts increasing (The process level RAM doesnt increase, but the total system-level RAM increases)
The GPU use is very low 
Rapid fluctuation in process-level RAM (250MB-700MB)
After a while, my computer would freeze/crash

With
gfx.offscreencanvas.enabled = true
layout.css.font-loading-api.workers.enabled = true

I get this regression range : https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=ba973417adb8c738b0ab57328fd28133c77bcf5b&tochange=a33cd50e2f73a5626864cd88e14d9fbd2ab158c2

suspect: bug 1765323
