This was a problem with WebGL a few years ago on some OS/GPU/Browser combinations. It was possible to write a WebGL app that created uninitialized textures, drew them on screen, grabbed a screenshot and then uploaded that via HTTP(s) to a server. This issue should now be fixed, but bugs and/or old unpatched browsers may still be out there.

That browsers have bugs that might leak info is not special to WebGL or GPUs. The bugs are found, they get fixed.

  Oh sure, but in this particular case it seemed like no-one had thought about the issue that uninitialized textures can be used for snooping screen content, this wasn't mandated by the spec (IIRC).
