I'm having the same issue. Even if switching back the layout in Zorin Appearance to "Windows 11 Style" the Ubuntu style remains. Plus Bluetooth-connection is unstable. Sometimes it suddenly stops working.
System:
- Zorin OS 16.3
- OS Type: 64-bit
- Windowing System: X11
- Graphics: Mesa Intel® HD Graphics 630 (KBL GT2)
- Processor: Intel® Core™ i5-7500 CPU @ 3.40GHz × 4
- Memory: 15.5 GB
