I had the same problem and I narrowed it down to either Alt Hud or sidepanels by Badobest. It's pretty rare so after narrowing it down to those two I just did without either of them, but maybe this helps.
The options I was using that caused the problem:
Side Panels by BADoBEST
Panel: BADoBEST v1
Alt Hud
Navigator
Navigator: hootorez style
Smoke counter (Alt hud)
Smoke counter: centered
