UNSUPPORTED (log once): POSSIBLE ISSUE: unit 0 GLD_TEXTURE_INDEX_2D is unloadable and bound to sampler type (Float)

Execute cargo ui on macbook m1(stable-aarch64-apple-darwin)：

UNSUPPORTED (log once): POSSIBLE ISSUE: unit 0 GLD_TEXTURE_INDEX_2D is unloadable and bound to sampler type (Float) - using zero texture because texture unloadable

I haven't seen this particular message before, but I've seen similar messages sometimes. When I've seen them though they were a warning merely, sometimes the result of drawing "zero" geometries.

Are you seeing this as an error message or is this just output but otherwise cargo-ui works fine?

I came across the same issue today, as I was using the SOIL to load texture, still don't know how to solve it

do you know how to solve it now?

[brezhart]

any updates?

[tronical]

@FloVanGH can you reproduce this on your Apple silicon machine? (Using the femtovg renderer, not Qt)

[FloVanGH]

@tronical

not that but I cannot build it.

With stable I can build and cannot reproduce the error of the issue.

[brezhart]

This error also happening when am trying passing texture using sf::Shader::setUniform. Can be related to that.

Could you elaborate what sf::Shader::setUniform is?
