A modern programming language that makes developers happier.

kotlinlang

that may be due to the fact that I use a tiling WM…

When I was researching window decorations, I remember reading something about it and I think there was a compile/runtime flag to add support for that case. I'll google a bit, but can't guarantee I'd find it

I can't find origin where I read it, but you might give `-Dcom.sun.javafx.transparentFramebuffer` option a try (wild guess from the results, can't even find docs what's this flag doing).

It doesn't change anything. (note that running xcompmgr works but not when using server-side rendering, so I'll just do that, X is such a mess anyway)
