Comment 1 Rémi Verschelde 2018-11-06 08:53:30 UTC

As far as I can tell it's due to the bogus Mesa 18.2.3 update on F29: https://bodhi.fedoraproject.org/updates/FEDORA-2018-bcdb732491

Many QA tests mentioned it was broken but Bodhi auto-pushed it to stable nevertheless. If the 18.2.4 candidate does not fix it either, the update should be reverted to 18.2.2 until a proper fix is found.

According to https://bodhi.fedoraproject.org/updates/mesa-18.2.3-1.fc29#comment-857231 the update is broken due to a GCC update.

Comment 2 Rémi Verschelde 2018-11-06 13:17:24 UTC

I asked an affected Godot user to downgrade to 18.2.2, and he confirms that it fixed the bug.

Both 18.2.3 and 18.2.4 (currently in testing) are broken.

Comment 3 Rémi Verschelde 2018-11-06 13:20:22 UTC

> 18.2.4 (currently in testing)

Well it was just pushed to stable. It's still broken though.

Comment 4 Rémi Verschelde 2018-11-06 16:35:40 UTC

Should likely be fixed by https://bodhi.fedoraproject.org/updates/FEDORA-2018-b73380a8e4 (18.2.4-2) which was just pushed to stable.

Could you confirm Clemens?

Comment 5 Clemens Albrecht 2018-11-06 19:24:22 UTC

Ok nice. I am currently not on my Laptop.
I will confirm it later this evening or tomorrow.

Comment 6 Clemens Albrecht 2018-11-07 08:51:13 UTC

I just installed the 18.2.4-2 update.
It seems to have finally fixed the issue.
Godot is working properly again.

Comment 7 Rémi Verschelde 2018-11-07 09:34:41 UTC

Thanks, closing as fixed by https://bodhi.fedoraproject.org/updates/FEDORA-2018-b73380a8e4 then.
