Using Toad for Oracle Beta x64 version 22.214.171.1245
Oracle Client 19c
Windows 10 Enterprise 20H2 (64-bit)
Using Color Scheme Carbon. I went to save an editor file. Upon returning to the editor, the menus, toolbars and icons all appeared to be inverted from the Carbon color scheme. See image below.
I had been using the editor for several hours, switching between editor tabs and saving/retrieving files w/o incident. To resolve issue I will need to restart the app.
