True, but looking at Activity Monitor I don't see any CPU or GPU spike when having an Electron app open and scrolling in Chrome (vs scrolling without any Electron apps open)

Apparently the issue has to do with transparencies (shadows and straight up transparency), so could be a question of capabilities not capacity e.g. older gens have less range and some non-default require falling back to software whereas newer gens can keep to hardware.

Watch your power usage. With large windowed VSCode or Cursor, you will see far higher CPU and GPU usage by WindowServer and more system power consumption. It’s easier if you track it with stats.app.
