Thanks for filing! Though, this is not the unity opt-in dialog (it's pre-unity).

I will check whether we have the same problem with unity enabled.

Ouch, I guess I didn't pay enough attention, and just assumed dev already has unity.

I couldn't repro on 73.0.3642.0 (Offizieller Build) dev (64-Bit) on Linux.

May be it's about the display resolution or font size?
I am not sure

Also can't reproduce with Unity enabled on the latest Canary on Mac.

Jochen, do you have a special font configuration?

I'll close this as it's not reproducible with Unity.
Please reopen in the case your issue also comes up with Unity enabled :)

will do.

For posterity, no, no special font configuration. It's a stock Ubuntu install.
