[Linux] Shadows disappear when set to "High" or above

Description

When set to "high" or "epic," shadows will render briefly but quickly pop out of existence upon entering the world. Setting to Medium or Low causes them to return. Does not appear to be a performance issue, as earlier builds rendered High shadows without issue. No FPS loss or stuttering occurs. Shadows render normally on menu and character select screens.

Status changed to 'Done'. Reason: fixed by resetting shader cache :)

Clearing shader cache appears to have fixed the problem!
