Simple text has jagged movement if on top of SPR

What is your operating system?
Windows 10 x64

What is your Shotcut version (see Help > About Shotcut)?

Can you repeat the problem? If so, what are the steps?
using a Text:simple on top of a SPR filter (to make the SPR move the text) causes visibly jagged movement in the entire text
Note: text rich does not have this behaviour


Quick test using a simple zoom in over a 5 second .jpg background (same thing if video instead of jpg):
