Problem with Dark mode in macOS Catalina with the new 2020 r1


In the last release (2020 r1), under MacOS 10.15.6 with Dark Mode turn on, the background of the windows are shown without Dark Mode (so white) and the texts are shown correctly (so white), this means it’s almost impossible to see something on the screen.

I’ve reset all settings and ensure Xojo app has all possible rights under System Preferences, Security.

Any idea of why this is happening?


It’s a bug and the team are aware. It’s a bit of a pain, but the workaround is to click the little “monitor” icon in the toolbar twice, the very right-most icon.

Thanks. I was not aware of it. It’s solving the problem.

I was looking for it, but I didn’t find anything… maybe I’m bad searching. Thanks for the info. However I’m not able to open the link you share… but don’t care, the previous post is solving the problem

Thanks for answering
