What is your operating system? Windows 10
What is your Shotcut version? 21.12.24
Can you repeat the problem? If so, what are the steps?
- Apply a Mask: Simple Shape filter to a clip
- Set keyframes to any of the position or size settings. Leave Rotation at 0
- Save as a preset
- Apply the preset to a clip.
When you play the clip, the rotation setting switches from 0 to 179.9%
This leaves very noticeable and ugly “steps” on the borders of the clip.
I noticed this bug in v21.12.24
Testing on older versions, I also found the bug in v21.12.21, v21.10.31 and v21.09.22 BUT not in v21.06.29.
