Not pressing any button or other interaction. System is running fine - enough memory, and have not experienced any issue similar to this before.

Hi, thanks for the report.

and have not experienced any issue similar to this before.

You mean using this package previously or the OS X system itself? I'm suspicious that this could be related to https://github.com/golang-ui/nuklear/issues/22, will investigate.

Hi @xlab, I meant that I have not had that issue system-wide - I work with OpenGL quite frequently, and the same with Go, so I thought I'd let you know that I have a feeling it's related to nuklear instead of my machine :).

xlab commented 6 years ago

@Velocity- I've reproduced and it seems that a bit of changes added with #22 causes this. Please update the package, should be resolved for now. I will find the root cause later. :)
