Croteam and Devolver Digital have issued via Steam a new patch for Serious Sam 3: BFE, fixing graphics corruption under OpenGL if game is minimized or "alt-tabbed" while it is loading content. OpenGL library can now load even if some vendor dependent functions are missing, and X11 libraries on Linux are now dynamically loaded, so game can properly report and error if something is missing.
