[Mel]

Attachment: about_support.txt

User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:83.0) Gecko/20100101 Firefox/83.0

Steps to reproduce:

Set gfx.webrender.all to true
Click on Adguard VPN icon in the toolbar.
Attaching about:support info.

Actual results:

When webrender is enabled Adguard VPN displayed a blank page. It was still possible to click blindly on the options (e.g. toggling the VPN on and off, changing the server).
It works normally with webrender disabled.

Expected results:

Adguard VPN panel displays normally with webrender enabled.

I've noticed this happens only when MOZ_ENABLE_WAYLAND=1

Here's the terminal output when clicking on Adguard VPN icon in the toolbar:

The release manager refused to uplift the fix. WebRender is broken for all Wayland users.

Who is the release manager for 83?
