Hey there, I know this is an old thread.

I have exactly this problem running an i7 with an older mobo. with plenty of processing power and available gpu memory/speeds etc.

did you ever resolve this on your own?

 I am unable to upgrade windows with my mobo and maybe using windows 11 or something like that would be better. I also have problems trying to undo multiple bezier lines in a row if it doesnt outright crash on the first try. 

I'm going to try and run the program on a Linux based OS and see if i get the same results. 

One like this was fixed recently by 1.2.1:  https://gitlab.com/inkscape/inbox/-/issues/6930
