In Google Chrome, navigate to:

https://www.khronos.org/registry/webgl/conformance-suites/1.0.2/conformance/textures/texture-size-limit.html

On my on my GTX 650, this causes the desktop to lock-up with the Nouveau drivers, but passes with the Nvidia proprietary driver. 

dmesg failure output:
[ 4183.336016] nouveau W[     DRM] skipped size 80010000
