GPU.zip: side channel attack that exposes visual data processed on the GPU
I had seen this happening. I was running webgl shaders in chrome in a pipeline where i was passing the result of the previous screen to be processed by the next, then sometimes I would get portions of other app windows inside the result with the post-processing webgl shader filter applied to it, which was crazy. I thought it was just a glitch on my system and couldn't replicate it reliably, it would just happen sometimes. Good to know it wasn't just my system :)
