[Solved-ish] SplitView.SplitGUI() huge spike every few seconds while playing

Hello friends!
I'm having an issue where every few seconds, (10 or so) my editor has a huge lag spike. This only happens during the game.

Here's the profiling during deep profile. Note the high GC.Collect as well:


I'm not sure what DockArea is. My only guess is it is where window tabs sit?

Anyone know how I can fix this? It's quite frustrating, since it makes playing the game in the editor very annoying.

 

I managed to figure it out. I decided to disable gizmos on a certain object (Astar pathfinding project) and the issue went away.
In other words, this was caused by gizmos being too thicc during gameplay. What I don't get is why this issue was actually shown in the profiler, not "SplitGUI()". I'm lucky I managed to find it.
