From 6869d2463a2e0d71bd04dbc82f5d6ef4933dc510 Mon Sep 17 00:00:00 2001 From: Eirik Aavitsland Date: Tue, 13 Apr 2021 14:23:45 +0200 Subject: Avoid processing-intensive painting of high number of tiny dashes When stroking a dashed path, an unnecessary amount of processing would be spent if there is a huge number of dashes visible, e.g. because of scaling. Since the dashes are too small to be indivdually visible anyway, just replace with a semi-transparent solid line for such cases.
