Wow, never had this, I use IntelliJ (for java) many hours everyday with 2x4k@60Hz screens (both running with hidpi scaling so even more pixels than 2x4k) and it’s always running smoothly. Running MBP 16”.

This has been my exact setup (except 15" instead of 16") for four years now, and I also have never had problems.
