Hello Alex Carol,

Thank you for the bug report.
I tried to reproduce your issue on Ubuntu 20.04 with workbench 8.0.28 but I am not seeing any issues at my end.

Regards,
Ashwini Patil

8.0.28 test results

I'm facing the same issue on ubuntu 22.04. Tried with version 8.0.30. I also tried installing older versions but same issue occurs. 

Issue is manifested when opening any model (new or existing). I'm unable to edit EER diagram objects nor edit tables in mysql model schema.

Opening test model results with this display

After doing a bit more tests I've found that issue is present only when "Fractional Scaling" is active. When disabled model can be edited properly.

Thank you Bernardd, changing fractional scaling config fixed this.
