HW : i7-3520M : ivybridge with intel GPU HD4000
Please describe your issue in as much detail as possible:
Steam Overlay does not work with performance optimisation option "mesa_no_error" set to true in ~/.drirc ; I just get an empty gray rectangle in upper right corner of my screen. Overlay works fine without this option.
I can consistently make the problem appear and disappear by turning "mesa_no_error" on and off.
It has been the case since at least Fedora 29.
I think I remember reading that this perf optimisation was contributed by Valve
