This looks like the bug https://sourceforge.net/p/sweethome3d/bugs/684/ and we have no way to fix it because it might be caused by other software. Please try stopping programs like Nahimic or Riva Turner / Discord / NVidia Experience monitoring display software.
Thanks, I turned off the riva tuner.
