btlac,
We compile most of our Linux offerings on Ubuntu 18.04, and while we don’t list 24.04 I have many reports of success from customers. I will update our website to reflect this.
We have tested Spike on 4k monitors before. Do you see the issue when you put Spike on the main laptop display? If yes, does anything change if you disconnect the external monitor? Can you verify you don’t have any outstanding video drivers you can install for your machine? I haven’t seen your issue specifically, (black screen related to window size), but have seen customers report fully white/black windows, and usually updating video drivers resolves the issue.
Regarding the other issue, it should not be an issue, this is a longstanding output that seems benign, and resists our efforts to remove it.
We have a very limited number of command line arguments, help is not one of them. They are listed in the manual, but are generally unrelated to your issue.
