[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Gtk' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

Apologies! Petr previously fixed this on Vulkan, but now we are exposing GLES3 as well on Linux (in a limited form), so the bug slipped in there. I'm taking care of it.

With following patch I'm able to build it again:

[BugBot [:suhaib / :marco/ :calixte]]

The patch landed in nightly and beta is affected.
:kvark, is this bug important enough to require an uplift?
If not please set status_beta to wontfix.

For more information, please visit auto_nag documentation.

Comment 9

[Dzmitry Malyshau [:kvark]]

This is a fairly big patch, which doesn't even do anything on Beta (other than fixing the build on Solaris).
Petr, how do you generally use FF on Solaris? Do you package the builds manually, apply certain patches, etc, or do you just expect it to work out of the box?
