corrupted size vs. prev_size in fastbins
This didn’t happen with the same project in Godot 3. Weirdest thing is, the scene works, but if it’s the second time the scene appears, that it crashes (sometimes). I’m not sure how to figure this out. Running with --verbose or from debug build doesn’t give any additional info
Are you running the 4.0 release version of Godot (as opposed to some earlier RC or beta version)? I ask as there’s a similar issue on Github that’s reported to have been fixed (maybe you’re already aware). In case not, here are the references:

Thanks for checking it out and replying! This happens in 4.0-stable as well as daily builds from master. I’ve been keeping tabs on commits and haven’t seen anything that looks like it would solve it.
I’m not sure if I can put together a MRP project or not. I’m wondering if there is a way to pinpoint the issue before having to attempt an MRP

Also I’ve combed through the .tscn files for issues. There are no TileMaps in the scenes. There are mostly menus, with some shaders, particle effects, and control/sprite menus. It seems like two simple menus are the culprit as when I delete them the crash doesn’t happen. But the menus are simple, so it doesn’t make any sense.

Turns out it was a bug in GLES3 textures.

Oh, nice - another one squashed. Thanks for the updating the post.
