Thanks for the report.
When you are overriding studio for high dpi scaling, windows is now scaling up Studio’s fonts. The problem is our application does not currently resize the UI accordingly, resulting in the text truncation you are reporting.
As Dave mentioned at RDC, we are currently working on proper High DPI support, so soon our users wont have to use the override option to get proper high dpi performance.
Unless this is majorly impacting you in some way, we will not have a short term patch for this, but we did confirm that this issue will no longer be present once we have high dpi support (Hopefully sometime early next year).
As a temporary workaround, if you decrease your scaling percent, the text will be less truncated.
