Thread For Your Useless Discoveries

[AlbertArmStain]

That's definitely on your end, it looks fine for me.

I had the problem in Chrome, and found that it also happened in Firefox. Further investigation revealed that it has to do with the zoom factor. I guess the viewer assumes that it's going to be a particular width, and doesn't take the screen width, so if the screen isn't wide enough to show all of it, instead of resizing it, it ruthlessly crops it. Changing the zoom factor doesn't fix it immediately, but reloading the page afterwards does so. (I haven't seen this problem with the pop-out viewer; possibly because it can occupy the full screen, while the inline viewer is constrained to the feed width, which has only the left part of the screen, with the right column being filled with user avatars etc.)

It’s probably a phone issue, I’m only getting that problem on phone

I'm using a web browser on a laptop. I think it has to do with limited available screen width, rather than the actual platform. Of course, phones typically have narrower screens, so they're more likely to also run into this issue.

Random fact: even though an R-pentomino gives a duoplet spark at generation 9, only a couple of known R-pentomino hasslers have sufficient clearance to use that duoplet to reflect a glider: one is p37 and the other p40. (The C2-symmetric p30 one emits reflecting duoplets in an unrelated way.) Neither of two allows for the following glider-producing spark interaction. (Again, the p30 one is obsoleted by an unrelated asymmetric p30 for the purpose, as seen in the pseudo p15 gun.)

Random fact two: the duoplet-emitting tub-with-tail eater reaction is not very suitable to the glider-producing spark interaction. Six (6) ticks prior to appearance of duoplet, an interaction destroys the eater.
