[GAMEPLAY] All HUD items slowly disappear after game starts

A few weeks ago I had a game where as soon as it started things started going wrong. First, the minimap disappeared(I don't have timestamps since I didn't notice until the HUD on the bottom left) and then the bottom HUD disappeared and slowly all my HUD items disappeared as well as my cursor. It made it almost unplayable though the buy menu was still working. This has only happened once and I only had to restart my client and rejoin the game but it was still annoying.
