I’m quite sure that’s not a driver bug. Reason for that is that Apple is well aware of the issue and that’s why it’s fixed in MBPs with 5600M.
If that would be solely driver bug it would be patched by now (and that’s an issue since 2019, so not exactly new).
The power/heat is due unnecessary clocking up when it isn't even doing any work. The non-dGPU version does better at the same task.
