So I’m trying to give more animation to my RPG status bar UI, which is stacked with Grid Panel. However, attempting to keyframe the grid rules causes the engine’s RAM usage to (quite literally) explodes from 1 GB to nearly 7 GB in an instant, and it stays there until it freezes my system entirely. This behaviour happens every time, persist across all 3 minor versions of 4.22, and I think it’s reproduceable. This makes loading 100 big sub-levels at once a tame job compared to keyframing a UMG Grid Panel.
With a bit of luck, this time my system is free from freezing after a while, without abrupt shutdown, and UE4’s crash reporter finally came out, but it has no idea about this behaviour, thus reporting about it having no debugging symbols or whatever.
What actually caused this to happen? Should I migrate to 4.23 to solve this issue (which I’m trying to avoid, preventing all the C++ scripts and add-ons from breaking), or just simply revise my UI guidelines to avoid animating grid panels in the first place?
