Toolbox 1.7 unusable via screen sharing on macOS

Since updating Toolbox 1.6 to 1.7 on my remote macOS host it has become completely unusable via screen sharing, not rendering correctly and showing only a shadow outline and some random image assets in random locations. Each time I try to use it the pane will render differently. Prior to this update it worked fine. Is it possible to download Toolbox 1.6 again so that I can verify that it is a regression with the latest version?
