I noticed on my 4k monitor running at that scaling the control interface often loses the menu bar.
Bringing the monitor down to 2560x1440 (2k) seems to resolve it, and I'll be using this resolution anyway but it might be worth looking at.
I can't use icon scaling on my setup as it messes with the EZD2 interface, but I'm good with 2k for easier reading despite not being at native resolution.
