Odds are the tube is clogged. With the tube clogged, the propane back builds pressure until the flame jumps to the start of the tube. Definitely not safe.
Either remove/replace the tube or just clean the tube in place. It has several slits which can be cleaned with a dental pick or thin metal finger nail file. Doesn't take much, just a stroke or two.
Sometimes they will have rusted out where the slots are holes but since you are getting back pressure, this doesn't sound like your case.
Also, take some air and blow up into the chimney to clean out any bugs. I actually remove my roof vent, cut out the molded in screen. This allows me to remove the air diffuser in the chimney and then swap with a piece of foam on a hanger. To replace the screen at the top, I bought a piece of gutter guard, bent the four edges, and notched for the screws. Make sure to only swap when the tube is cold and to replace the diffuser.
