I'm on Windows 10 x64 and using a Wacom intuos 3.
Affinity Designer about screen shows version 1.5.0.2
I've enjoyed testing this today. Here are some issues I've run into:
1. The first "drawing action" in a document is laggy and sluggish. Among the tools I've tried this has happened with vector brush, pencil and rectangle tool.
If the first thing I do after creating a document is pasting shapes from another document, the next "drawing action" action will be sluggish.
Subsequent actions are smooth, but if I undo back to just before the laggy action, the next action will be laggy again.
2. When drawing multiple lines using the vector brush with pressure controller, and applying light, even pressure, about every 10-20th line would disregard pressure and draw the line with full pressure for the whole line. Checked if I had the same issue in other programs, but didn't.
3. Had some difficulties activating pressure controller in some documents, but not sure what I did to cause that.
4. Had a few issues with the add and subtract operations. Expanded about 20 strokes and added joined them together. Needed two steps to get a "clean" add. Tried making a large square and subtract the added lines from it and it resulted in many extra tiny shapes which I had to delete (I think they were all tall triangles, but I'm not sure).
5. +1 for the simplify path feature request :)
