OSX Preview: Bug in the size of PDF Highlights
I can't seem to avoid this problem, but I can get around it by restarting OSX Preview when it starts happening. When I reopen OSX Preview highlight works as it is supposed to (normal hight on highlights). Note: If I however save the PDF with a faulty highlight, the faulty highlight will still be there when I reopen the PDF – new highlight will work fine, but old ones are not corrected by saving and restarting OSX Preview.
