I don't recall seeing any bug reports about inks/transparency on Linux -
could you elaborate?

In terms of number of lines of code to achieve the effect, perhaps - but
not for the poor CPU...

Any control which has an ink other than srcCopy has to be rendered into
an offscreen buffer before it can be composited into the parent. So,
technically, the CPU would be happier if the colors used in the first
place were just inverted ;)
