Crash (unable to read memory) when one specific filter is above another

Bug
1

What is your operating system?
Windows 10

What is your Shotcut version (see Help > About Shotcut)? Is it 32-bit?
21.01.29. It is 64-bit.

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.)
Yes, I can duplicate the problem in Dell T5600 every time, but I can’t duplicate it in HP Z600. This is very strange.

  1. Add a video (to a video track) and select the video
  2. Add the filter: “Fade In Video”
  3. Add the filter: “Size, Position & Rotate”. Resize the video to smaller box at upper right corner.
  4. Make sure “Fade In Video” is above the “Size, Position & Rotate”.
  5. Save the .mlt and open.
  6. Shotcut crashes.

This may help you ?
This should normally be resolved with your version.
Place the Fade filter after Size, Position & Rotate
