Hi! Thanks for the additional information. We have tested the latest nightly build, reinstalling it from scratch in the itch.io app, downloading the .zip and running from the extracted folder, and can't seem to reproduce the problem. Can you provide additional screenshots (preferably showing the entire app window) so we can analyze it further?
Also, are you running a multi-monitor setup with different display scaling for each display? For example: one display is 1920x1080 with 100% display scaling, and the other is 4K with 200% display scaling.
Below is the screenshot of our testing with the app freshly installed:
We're really sorry for this problem. Hopefully we can find a solution as fast as possible.
