Are there any news or indications already besides this thread maybe, or something I missed? It's quite annoying and a showstopper tbh.

 Nothing I've heard of, except some people over LE forums confirming the issue for the NUC7C/P series.

Best option is still something @HiassofT suggested a few weeks ago: File a bug report with some major distro (e.g., Ubuntu), so that they can/will hopefully fix it and LE guys can then backport/merge it.

Did anyone test with 4.18-rc1 #0627x? No idea if it's fixed, but worth verifying. Unfortunately we currently have no clue what is causing this issue, so we can only hope someone else finds and fixes it.

Alternatively use a cheap IR dongle (link is for illustration purposes only) as the Ortek VRC-1100 works very well (far better and more responsive than the built-in Intel CIR, to be honest, and works fine with Harmony).
