I was drawing a commission on Affinity Designer (running MacOS Big Sur 11.2.1) when the eraser tool started only working partially, it was transparent now. I fiddled about with settings and checked some forums to no avail. This is when I decided to get a photo as evidence of the problem.
The photo shows several lines in 3 different brushes, the first I left alone, the second I went over with the eraser one and the third I went over twice. It was on the second trial of the pen brush my eraser magically started working after no change on my part, and to illustrate this I erased the top part of all the lines. Bearing in mind this lasted about 20 minutes and fixed itself on it's own I can only assume it was a bug and to report it. The opacity and flow were both at 100% the whole time and I don't believe I've ever changed that, and opacity under the colour wheel was kept at 100%.
