Moving text on a video

Hello,
Just made small test to make moving text on a video.
Used the simple text filter, only changed the default (Verdana) font to “Bahnschrift” font and the text on the video was ‘jumping’. Changed back to “Verdana” and the text moved smoothly. That font is in the program’s fonts list, so why is it ‘jumpy’.
All settings remained the same, just font changed.
By the way, the slideshow was done with some other program.
Attached two video (mp4) samples:
Sample-1A with “Verdana” font
Sample-2A with “Bahnschrift” font.
Answers will be appreciated.
Thanks
Motim
Program version 19.10.20
Note: I’ll try to upload the samples one by one - some limits.https://forum.shotcut.org/uploads/default/original/2X/9/932c11357ad001ebfdd7bf210e52a1f90b08adea.mp4 https://forum.shotcut.org/uploads/default/original/2X/b/ba5ccd7f662263194f232d0dba1f90c01649e4c7.mp4
