Public Service Announcement: latest mesa in @debian testing (22.2.4-1) breaks gtk4 and qt apps (not gtk3 ones as they don't use GL). We will upload a fixed package to a Mobian repo later today, so hold on upgrading for a day or so. Thanks....
And immediately after noticing the breakage, @awai uploaded a fixed version of mesa to our staging mobian repository. We will file an issue for the version in @debian as well, of course.
Unfortunately, I had upgraded before I saw the post. Thanks for the quick fix!!! Also, Happy Thanksgiving day. I am thankful for volunteers like that make open source software great!
