[Driver 343.13] 32-bit rot?

Graphics / Linux Linux
1

on my optimus laptop (64-bit) 32-bit opengl applications that use nvidia’s libGL.so error with a segmentation fault, 64 bit opengl applications run without any issue, similarly i have no issues running mesa with the intel driver, but for much of my steam library this is sub-optimal, i suspect bit-rot in one of the 32-bit nvidia libs.
how can i correct this?

sure,
my install command
sh NVIDIA-Linux-x86_64-343.13.run --no-x-check -a --opengl-libdir=nvidia/ --opengl-prefix=/usr/lib64/xorg/ --compat32-libdir=nvidia/ --compat32-prefix=/usr/lib/ --x-library-path=nvidia/ --x-prefix=/usr/lib64/xorg/ --dkms --no-recursion --x-module-path=/usr/lib64/xorg/nvidia/modules/

and the nvidia-xrandr start-up script

xrandr --setprovideroutputsource modesetting NVIDIA-0
xrandr --newmode "1366x768"   85.25  1366 1440 1576 1784  768 771 781 798 -hsync +vsync
xrandr --addmode VGA-0 1366x768
xrandr --auto

exec xterm

to start a new xserver with off loading
xinit ./nvidia-xrandr – :2 vt2 -config xorg.conf.nvidia

and to play games with direct rendering (64-bit apps)

if you need any more details i’d happy to provide them
