I have noticed the exact same thing with all of mine LC-513 (Dolam) tubes. When i pop them in a clock on the seconds place, they all the numbers tend to flicker, some will have stable glow faster than others, it usualy doesent take longer than 30 seconds for all o them to glow fine. I asume that the multiplexing plays some role in this too. Ive also seen some neon bulbs that have this sort of weir flickering on them (im not relating to that AC flickering) the glow of one of the bulbs in my clock tends to jump up and down on the cathode. If i have them turned off for a longer time before turning on, the flickering is really slow, it jumps up and down only like once per second, but soon after that it starts to excelerate to a poin when it all really unstable, it jumps up and down like six times per second! The weird thing is it happes only on one bulb! The other glows just fine. Ive seen this on some youtube videos too, so im not the only one. Does anybody know whats the problem with that?
