Kindly request your attention for a really annoying visual Java bug on Linux Mint

[Stefan Reich]

Dear Sirs or Madams,

I make a visual recognition tool <https://gaz.ai> in Java that would
tremendously benefit from the ability to show translucent windows. Indeed,
Java has such an ability but it is broken on my Linux Mint 19 ThinkPad for
unknown reasons (screenshot <https://botcompany.de/images/1103064>).

All the details are here:

I'd love to see this fixed. Not sure how reproducible it is or if there is
anything screwed in my Linux Mint installation. Seems to run fine otherwise
though.

Many greetings,
Stefan Reich
