Godot version

4.0.rc3.official [7e79aea]

System information

OS: Arch Linux, CPU: i7-3770, GPU: Radeon RX 570

Issue description

Simple project using HDR texture as PanoramaSky exported to Linux crashes when opened. Might or might not be related to #73627 and #61948.

Output displayed in the console when opening the exported game:

Steps to reproduce

Try to export the provided project.

Did you export the project using headless mode? There's a known issue with VRAM-compressed textures not being exported if exporting using --headless --export.

@Calinou No, directly from the Editor.

The errors look suspiciously similar to the errors in #73267 which was closed as a duplicate of #72856 which was fixed by #73286

[akien-mga]

I could reproduce the issue, which is caused by the export preset having texture_format/bptc set to false.

Setting it to true fixes the issue (note that in RC3, the import for the .exr file is extremely slow - this is fixed in RC4 by #73715.

The option should probably default to true, at least until we have a proper detection mechanism that lets users know that they are actually using BPTC and should therefore enable export it.

I'm not sure what's the purpose of this export preset option in the first place though. It should export what it needs.

[Regrad]

The bug is still present in the RC4 version. Importing an uncompressed HDRI texture solves the problem.

[akien-mga]

Yes, it's mentioned in the RC 4 blog post with the workaround: https://godotengine.org/article/release-candidate-godot-4-0-rc-4/#known-issues

The fix was merged after RC 4.
