RDM undocked tabs unresponsive after application lock / RDM version 2020.1.17.0 64bit Enterprise

Hi,

I would like to report a strange bug I am experiencing with my RDM version 2020.1.17.0 64bit Enterprise. I am using the screen lock after inactivity, where after a specific time RDM locks the user interface. I am using Google Authentificator to unlock my workspace.

After unlocking and while using multiple undocked tabs across other screens, the user interface of RDM is completely frozen until I close all undocked windows.

Additionally, on my undocked screens a black box is appearing (see attached photo).

Would you be so kind and take a look at this problem, or is there anything I have to change in the application to avoid such behavior?

Thank you very much for your support and care.

Kind regards

Boris Garami
