The SU 12 Release notes mentioned better cloud alignment of thermals.
But in fact the opposite is the case. Thermals are more offset from clouds than ever.

And it is NOT just the visualization. This is actually where you’ll find lift when flying a glider.
This was reported during SU12 Beta, but not fixed.
With several months in between iterations in the various Sim Updates, it will be a few years until MSFS has a realistic thermal model. Especially if reported bugs are not being addressed.
