Find and Replace display bug

After entering a value in the first field, hitting Tab to go to the next field makes the first field data vanish.
As I go back to the first field, the bottom field looks empty.

this doesn’t affect performance - just looks bad…Find%20A Find%20B

My version is Version 2.6.5 (1325).

I have that same version and it works OK for me.

Which macOS version are you running?
And which locale (language) is the system set to?

MacOS 10.12.6

I have the feeling it is related to the macOS version. I don’t have an old installation at hand though so I can’t confirm.

I will upgrade my OS. No known issues with Glyphs?

Don’t upgrade just because of this. I’ll see if I can reproduce it in 10.12.
