print hotter 190 ?
wow. Don't think I've ever printed pla lower than 200 and 210 is my standard for 90% of prints.

Corners are lifted because you've got shrinkage - it's slightly fatter due to the 'smoosh'.
With some filaments you can't get round it.
But try printing it at 210.

Also fan off for first two layers and print the first layer very slow.
