I'm running both SEQ5 and SEQ6 side-by-side (not at the same time, obviously) on a Raspberry Pi 4-4G and while SEQ5 is super snappy compared to what it was on the Pi 3B+, SEQ6 is very slow, to the point it's almost unusable. Not sure what information I can offer to help analyze the issue but if you have any ideas I'm happy to try. I've tried exporting the display to different PC's but that doesn't make any difference.
