Rounded window corners obscure guest's screen content

[neldredge]

On MacOS 26, the rounded corners on the window of a VM obscure some pixels from the guest's screen, which can be problematic if you needed to be able to see them.

Note that the n in the corner is partly obscured and nearly unreadable. In some situations it might be important to be able to read that character clearly.

This is a macOS issue which affects every app compiled for macOS 26. There are external tools that exist which claims to solve this problem that you can look into.

So you don't think it would be reasonable to work around it by adding a "margin" of some extra space around the edge of the guest's display? Terminal applications do this, for instance.

Okay if that's what you mean, then sure
