I'm running Lazarus 9.29.?? (rev 26163) with FPC 2.4.1, so yeah, there are new features that don't exist in the 9.28 builds.

Can't see your screen shot to see what your talking about with the "face down" part. If I get a chance I'll see if I can spin up a Linux install and try running the app in there. Since your using Ubuntu you can use APT package installs, maybe I should put one of those together for this project
