Sorry, but my word "invisible" was not accurate.
When the first user is logging in, pen tool cursor (or brush tool cursor) apparently sticks to the edge of canvas.
But, it seems to exist inside a canvas in fact, because a cursor suddenly appears in a canvas when I click a mouse button.
And, when I release a mouse button, a cusor disappears again and appears just outside of a canvas).
I'm trying to avoid this problem, but I can't find any work around solution.
- It never occurs when a first user is NOT logging in.
- A first user never meets this problem, even when I'm logging in.
- Removing the prefs file in ~/Library/Containers is not effective.
- Hardware GPU preference never affects this problem.
- It never occurs when I use on MacBook Pro late 2013 (without discrete GPU) as a second user.
Please tell me if you have any idea to avoid this problem.
