A Relatively Recent Core Error Causes GUI Memory Leaks Overtime

Reproduction Steps
I’m unsure if it happens in all games, or just games using SurfaceAppearance or Skinned Meshes but I’ve noticed it in several games now including my own projects.

Expected Behavior
Normally core errors don’t pose such an issue, but this error message is LONG and consistently repetitive. I would expect core system errors not to affect performance, however this one does.

Actual Behavior
This error is spammed in the log repeatedly, until eventually Roblox as a whole becomes unplay-ably laggy showing a huge amount of usage going into GUI memory even if the client doesn’t have the log open. The players who have noticed this have been in game for several hours without rejoining, so to be fair it’s not affecting the average user.

I have no workarounds for this issue.
