A recent updated to Manjaro/Arch has caused the Godot Engine t= o lock up when it calls glLinkProgram. This appears to be a Mesa 18.3 bug as the issue has started recently and so= has 18.3 been rolled out recently in Manjaro. Here are URL's to bug reports on the Godot forum that should provide further information: https://githu= b.com/godotengine/godot/issues/24362 https://githu= b.com/godotengine/godot/issues/24783 https://githu= b.com/godotengine/godot/issues/24340
Can you try to bisect the commit where things chnages between = 18.2 and 18.3?
This issue seems to be affecting me too, some people say it's = been fixed in 18.2.3/.4 however I'm running 18.3.1 and definitely have the same symptoms = in regards to Godot freezing up, I don't know much so can't be more help, there seems to be some discussion relating to the issue here though: https://b= ugzilla.redhat.com/show_bug.cgi?id=3D1646888

That one wasn't a Mesa bug it was a bug = in GCC.

Well I have no idea how to use Godot and couldn't follow the i= nstructions in the linked bug reports. So can someone attach a sample project here and instructions to trigger this problem with it? Thanks.
Hi Tim, sorry about the slow reply. I've added instructions on how to reproduce the problem here: https://github.com/godotengine/godot/issues/24783#issuecomment-45= 3380560 Download build.zip and it has everything you need in there. How would I go about bisecting the changes between 18.2 and 18.3 where thin= gs went awry?

apitrace of godot including glLinkProgram lock up
I don't know how useful this is in this situation and I haven't done it bef=

now but I've managed to get an apitrace of it happening inside of Godot,
happening around frame 540 or 541 when I enable emission on a material (tho=
ugh
the freeze happens on any shader change if it's changing for the first time=
on
that build of Godot), hopefully this can help in some way
Just for clarification I am running 18.3.1 on Arch too
