How was this texture asset created? The texture is a cubemap with 4 array slices which is strange.

Never mind that, was looking at the wrong place in the debugger.

I didn't have an actual skybox. So I used the option to import a single texture as all the skybox faces. bs::CubemapSourceType::Single

I cannot reproduce this issue, tried with OpenGL on Windows and Ubuntu, using the Skeletal Example and the provided cubemap asset, both debug and release build configurations.
It could be something hardware specific. What is your GPU?

That's the same as mine. Since I cannot reproduce the only option is you to debug it on your end. Try breaking with the debugger when it crashes and see if you can deduce in more detail which part failed and if any of the input values look weird.

To me everything just looks initialized, and with possible sizes:

(gdb) p data.getSize()

Edit: except it looks like the data buffer size (67108864) is different than the texture's size property (16777216)...

Is your app running on an older version of bsf, but the texture was imported using a newer version?
That would explain what I'm seeing:
mBuffer.mSlicePitchis 4194304, which is the number of pixels, not bytesdata.getSize()returns the 4 times the required number of bytes (again, its interpreting themSlicePitchas the number of pixels and then multiplying by 4 to convert to number of bytes)
Meaning of mSlicePitch was recently changed to store number of bytes, which would explain the discrepancy.

commented on June 20, 2024
That is likely correct reasoning. I'm using the default version of the samples, with the version of bsf it's set to use. git submodule update does nothing. But the asset was imported with the version my PR (#391). Then, this is different from the (likely) timing issue with the skybox loading causing a crash.

I have not gotten this crash after I did this change: https://discourse.bsframework.io/t/resource-caching-doesnt-work/499/10?u=hhyyrylainen
That may have fixed it? Maybe it was an issue with something not waiting for the resource properly without registering the asset path?
