The window select feature on Orion's toolbar is mangled and hard to select on Catalina in the latest RC. I noticed in previous versions (e.g. 1.0.3) that the full window name wasn't shown (e.g. I would see "Private Win" rather than "Private Window 1") but it was still usable.
Here is a screenshot showing the window label apparently wrapped such that it can't be seen:

Note that on Monterey (M1), the window label is blank and unselectable. However, the window label works fine on Sonoma (M1).
I expected the window label and select feature on Orion's toolbar to work on the same on all versions of macOS (e.g. Catalina and Monterey but also Mojave, Big Sur, Ventura if applicable) not just the latest.
