Codex is one of the most infamous examples of slopware. Just having the window unhidden on my mac will cause it to use 100% of the GPU displaying the spinner message. THE SPINNER MESSAGE CAUSES 100% GPU USAGE ON AN MBP M5!! So any time you're waiting on the model (which is 90% of the time), your fans will be blasting (careful, don't use it on battery). The issue is on github and close to 6 months old. Probably since…
