Preview Frame drop frames while playing

[Falconz]

What is your operating system? WIN10 64

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
20.09.27 No

Can you repeat the problem? If so, what are the steps?
(Please be specific and use the names as seen in Shotcut, preferably English. Include a screenshot or screen recording if you can. Also, you can attach logs from either View > Application Log or right-click a job and choose View Log.)
1080p 60fps
If a video segment doesn’t fit in the timeline bar at the bottom, the preview frame drops frames as it scrolls across. It can be avoided by “zooming out” on the timeline, but this is a workaround not a fix.

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.
