Bubbles question

[vNmd]

I have a belgian (wpl400) that I have some strange bubbles. Fermentation is complete and I just haven't transferred to keg yet. I opened it tonight and instead of seeing the usual smooth surface after krausen drops, I see the stuff in the picture. It has been 3.5 ish weeks since I pitched. Any idea of whats going on with the bubbles? I have made this recipe before and didn't have these.

Looks like CO2 coming out of solution. Completely normal.

Looks like left over krausen to me. Nothing wrong here...

Looks fine, close the lid! Maybe I'm just paranoid about introducing an infection or something to my beer, but I never open my buckets until I'm ready to transfer or bottle.

I got really nervous once seeing something similar on a beer I had sitting in secondary for 4 weeks. It's going on 7 months in the bottles without a single gusher (in fact they stayed nice and low carbonation like I wanted them) and not a single bottle bomb. Just CO2 coming out of solution and sticking on the surface.

Thanks all. I am used to seeing a nice clean top after that period of time. I usually don't even check until the 3 week point. Was a surprise.

Thanks again.
