1687096 - INVALID_OPERATION On copyBufferSubData Causes Machine to Lock Up

Status: RESOLVED FIXED

(Core :: Graphics: CanvasWebGL, defect)

Description

[connorwadefitzgerald]

Attachment: Contains ff debug information as well as repro case in "generated" folder

User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:85.0) Gecko/20100101 Firefox/85.0

Steps to reproduce:

Download the repro attachment. Launch a simple webserver serving that folder (python's doesn't work here due to mime issues; I used ruby's ruby -run -e httpd generated -p 8000). Navigate to the webpage in chrome, this will show a INVALID_OPERATION, as expected. Navigate to the webpage in firefox.

This is running wgpu-rs running in webgl2 mode, trying to run the cube example.

Actual results:

On my machine (win10/nvidia/ff85), it caused my entire machine to lock up, causing my cpu fans to go crazy, and causing me to need to hard reboot.

Expected results:

This operation should return INVALID_OPERATION.

Testing locally on Win10, this seems to safely INVALID_OPERATION and the tab (and machine) stay responsive.
Can you retest? Sorry about the languishing!

Redirect a needinfo that is pending on an inactive user to the triage owner.
:jgilbert, since the bug has high severity and recent activity, could you please find another way to get the information or close the bug as INCOMPLETE if it is not actionable?

There was an ANGLE update in ff87 and again in ff94, which probably fixed this.
