This is a very specific issue. When trying to swap components between two files, the list showing the projects and files gets cut out, even in high DPI screens. I attached a screenshot taken from my 4K monitor so you can see the problem:
You can see that I can scroll the list down but not up, so the projects starting with the first letters of the alphabet can’t be accessed. The workaround is to temporarily rename the target project with another letter, but, well, it’s a workaround.
This is just a bug report and I wonder if anyone else has had the same problem.
