I have 4K display, and I now do not see the truncated menu on the 26120.2222.
What display adapter and driver?
What scale and screen resolution settings?
Edit:
You have a Scale of 200%, that is why you don't see the problem.
The announced fix only works with Scale of 100%, 200%, 300%.
Fails with 125%, 150%, 175% etc. π΅βπ«
