This was recently reported and significantly improved for the next version 20.10.

V20.10 BETA now available for test

BETA 2 I have just published a beta 2 version 20.10.24 and updated the link in the top post to it as well. The beta period was always supposed to last until October 30, and that was fixed in the top post as well. I do not expect to make nearly as many changes as I did this past week. Now, only the most severe regression bugs will be addressed before release on either 30 or 31.
