Zorin 15.3 with HiDPI monitor and lower resolutions

I am enjoying Zorin. But I have a small monitor resolution issue.

I have a Dell XPS13 with a HiDPI monitor. When running in the maximum resolution, everything is fine. Some apps do not scale properly, so sometimes I lower the resolution.

However, in lower resolution when Zorin resumes after the screen is locked, both Firefox and the Files app (and sometimes the desktop) behave in strange ways. Part of the window shows a zoomed-in version of the browser/file manager that does not respond to clicks, while the actual portion of the window that I can interact with is much smaller (maybe less than 25% of the window). If I close the app and reopen it, the problem goes away.

It’s not a major issue, but it does take away some of the polish of Zorin. Not sure if this might be a Gnome bug or what, but I thought I would report it.
