https://www.hertzbleed.com/gpu.zip/ wrote:GPU.zip is a new type of side channel that exposes visual data processed on the graphics processing unit (GPU). This channel exploits an optimization that is data dependent, software transparent, and present in nearly all modern GPUs: graphical data compression. We present the first security-centric analysis of this optimization and demonstrate that it can be abused to leak visual data. For example, using GPU.zip, a malicious webpage can leak pixels from another webpage in the latest version of Google Chrome, violating the browser security model.

Likely, yes. We tested integrated GPUs from AMD, Apple, Arm, Intel, and Qualcomm and one discrete GPU from Nvidia. We have at least preliminary results to show that all tested GPUs are affected.
