The last update
"[SPECTATOR]
Player xray glow now dims when player is not making any audible sound. Several convars are available to tweak this behavior; “find spec_glow” for a list."
Was it changed glow process,and caused the glow flicker?
Decreasing the sleep time in loop can't completely solve the problem.
Been over a week since last update/bump after answers, assuming solved.
