Status: NEW

(Core :: Graphics, defect, P3)

Description

[Timvde]

Attachment: {dc3dce74-bf98-4eb4-adc4-75597edb6c5c}.xpi

STR:

1. Enable hardware acceleration and GPU process: set `layers.acceleration.force-enabled` and `layers.gpu-process.enabled` to `true` and restart Firefox
2. Install Tab2QR add-on: https://addons.mozilla.org/en-GB/firefox/addon/tab2qr/
3. Click on the extension icon

What happened: crash :(

What should have happened: no crash, duh :P

Crash report: https://crash-stats.mozilla.com/report/index/b8fde0ef-fe26-405b-b70b-77d480170825

I only have Linux to test, so I don't know about other platforms.

In case the add-on gets fixed in an update to work around the crash, I have added the xpi file as an attachment.

Note: I *don't* have WebRender enabled. I can also trigger the crash on Dev Edition, which afaict doesn't even build WebRender (about:support says "unavailable by runtime: Build doesn't include WebRender").
