2-UP Vertical window mode creeps wider with every click

[Pockitz]

I submitted this as a bug, but is there anyone else that has seen this problem before?

1. Using Indesign 18.2.1 on an M2 Macbook Pro with OS 13.
2. Open two documents and then select 2-UP vertical window mode
3. I expect both windows to stay the same width that I have set when opening 2-UP vertical window mode.
4. When using 2-UP vertical screen mode, the left hand window creeps wider by one pixel every time I click in the right hand window.

This screen capture shows what happens. the window on the left expands and the one on the right contracts with weird pink screen issues. What's happening? It's ruining my day 😞

Since your first post in April, did you update InDesign 2023 to its latest version, as well as macOS to 13.6.x? (Just don't upgrade to macOS 14 Sonoma).

I have a Indesign 2024 19.0.1 and Sonoma OS. It still does the same thing. Why should I not upgrade to Sonoma?

There are still serious display issues that Apple has not fixed.
