Hey @ashivkum! Thanks for reporting this and for your patience while we are working to get a stable version of Orion out. We had a problem with the Sparkle auto-updater with the latest RC, and it seems to have pushed an older build of Orion (i.e. a version that was built for macOS 14) instead of pushing the build that was built for macOS 26.
This is the reason you are seeing this bug (along with other issues where the location bar does not seem to have any background, etc.) We have already fixed the auto-updater issue internally, so everything should be okay next build onwards. But for this current RC, we have posted a link to the "correct" (macOS 26) build on Discord in the Orion-RC channel. Please try downloading Orion RC manually from there.
Again, apologies for this issue - and we really appreciate you sticking with us and providing feedback.
