I don't really see where the fix you mentioned is included? pop-os/cosmic-text@542b20c...58c2ccd
It also seems like you forgot to git add Cargo.lock, since fontdb got downgraded in cosmic-text (which unnecessarily reverses a performance optimization when loading fonts).

In any case, if you'd like to update cosmic-text I'd upgrade to 6f78d23, which includes multiple bug fixes by switching to newer versions of dependencies.
And I'd also cargo update -p swash

@apricotbucket28 the change downgrades fontdb to 0.16, which was the last version before the regression (which was introduced by the performance improvement). I am currently waiting for this fix to merge before opening PRs on cosmic-text (and eventually here): RazrFalcon/fontdb#68

@jcdickinson Thanks for this! It looks like the fontdb change has been reverted, is there a newer version of cosmic text without the regression and with the performance improvements?

[apricotbucket28]

It seems like this is waiting on pop-os/cosmic-text#296 to land. I guess the Cosmic team is busy since they launched their DE alpha not too long ago.
Maybe cosmic-text could be pinned to the commit hash from the PR?

This PR will also need to update resvg to 0.43, as that has a transitive dependency to fontdb.

This PR will also need to update resvg to 0.43, as that has a transitive dependency to fontdb.

That shouldn't be necessary, since the text shaping feature of resvg is disabled in GPUI.

Closing this for now, but let's reland it when upstream is in a good place.
