Encountered an unusual problem whenever I attempt to use my horse, my framerate tanks crazy just mounting on it. F3 Menu also seems to be bugged whenever I try to mount; issue goes away after demounting.

I've checked if BetterF3 was a culprit but it seems not since the Vanilla F3 menu also gets bugged out along with the same FPS tanking behavior. I've attached the corresponding log to the play session and a video demonstrating the lag.

Lot of logging than the usual from what I can see. But aside from mounting on a horse, other mountable entities like Immersive Aircraft seem to play nicely with AutoHUD.

(EDIT: Uploaded correct log file that matches with the video)
debug-2.log

(EDIT 2: Comparison log without AutoHUD)

UPDATE: Just disabled the improved_mount_gui on the Horseman mod and the issue doesn't occur, would be a case of partial mod incompatibility as a result. Another mod seemed to have a related issue w/ Horsemod that had the same workaround/fix.
