Since last update (v15.66.5) I am getting white screen on main TeamViewer window.
Other windows works fine when opened from tray icon.
If I close and open TeamViewer from tray icon, it works fine, sometimes I need to repeat operation twice to work.
This issue happens when computer goes idle, turn off monitor or switch monitor pattern (for example, when add a dock to add/remove monitors with different resolutions)
Please check it out. Follow screenshot including main screen without content and additional window properly draw.
