If going back to Mesa version 21.3.5-1ubuntu1 from Ubuntu reintroduces
freezes then I suggest that needs to be debugged by KDE/Plasma
developers.

It sounds like the main problem is still Mesa.
The i7-640M is a "Gen5" Intel GPU apparently:
https://en.wikipedia.org/wiki/List_of_Intel_graphics_processing_units#Gen5
That means Mesa should select the "i965" Mesa driver for it:
