Had this on my Qidi X Pro... quite annoying.
But only with 1 particular filament. A PETG from Real (Dutch brand).
Same brand, different color -> no issues...

I slowed down the print speed, That helped for sure.
I also replaced the nozzle, as it was suggested by Qidi support (and they sent me 2 nozzles free of charge!). But I dont remember of that really helped .
Slowing down for sure helps. Or use another filament.
