Text cursor on Mac with Retina Display incredibly thin
The text cursor ist extremely thin on a Mac with Retina-Display. In an empty text box the cursor is nearly invisible, having the same width as the frame of the box. On a regular display, the cursor has a much better visibility. You should auto-detect the screen resolution and choose an appropriate width for the cursor or you should let the user choose a size in the preferences.
