Apology because this is a vague question, but: is there something wrong with the convolution code in Flux?

Looking at the results of this example [https://github.com/avik-pal/FastStyleTransfer.jl](https://github.com/avik-pal/FastStyleTransfer.jl) , they just do not “look right”. (I think there is an interactive example of this somewhere on flux pages but cannot find it).

And 1-2 years ago I also vaguely remember some comment I read, maybe on here (Discourse), that suggested that there was a problem in convolutions, but also cannot find that.

Flux does have a number of [registered issues related to convolution](https://github.com/FluxML/Flux.jl/issues?utf8=%E2%9C%93&q=is%3Aissue%20is%3Aopen%20convolution). I guess you could look there.
