The time taken to expand dashed strokes using Layer > Expand Stroke gradually increases as the second dash value decreases eventually causing Affinity Designer to hang when the value is 0.1 or lower. This becomes more noticable when the second dash setting is around 0.4 and below. When we reach a setting of 0.1 the spinning beach ball is invoked as Designer hangs but that doesn't appear in the screen recording itself as Quicktime doesn't record it.
Note: Designer hangs but doesn’t crash so there is no crash report generated… this results in having to Force Quit Designer.
