    Title: /debug usage is causing hitching and performance issues
    Reproduction Rate: 100%
    Blocker? Yes
    Details: Don't use /debug - even if you flip it back off using /debug again - afterwards, hitching will start, that will progressively get worse - also noticeable when hitting ESC and to go in/out of the Options menu. (The game is spamming warnings about the particle system: Particle System is trying to spawn on a mesh with zero surface area)
    Steps to Reproduce: Use /debug for a few seconds, to see the warning message spam - turn it back off using /debug -- play the game for a while now - hitching gets progressively worse.

    The /debug UI uses the legacy Unity UI system that can severely impact client performance. I was able to verify that turning off the debug UI does remove that debugging UI, and is no longer running.

    Gotcha - thanks! It seemed a lot worse than usual -- also still seeing that constant log spam for the Particle System - it's dumping it to output_log.txt also - so it's causing extra disk IO as well.

    Would you please post some of these log spam messages?

    @Lord Subtleton - sending you the full log in a PM - but it's mostly a lot of these:
    Particle System is trying to spawn on a mesh with zero surface area
    (Filename: Line: 1527)

    Thanks. We've determined that the spam is coming from a character effect, one of those "shield of *" variants. Issue #62899.
