I have experienced the following problem (GD 5, Win 10):
All fonts of the GD interface (register cards, editors, piskel etc.) get blurring as soon as I start to work.
Right after startup everything is fine, but as soon as I open an editor or Piskel fonts become unclear and unreadable. The effect lasts until I move the mouse pointer over the blurred font. It then gets clear again - while other fonts become blurred at the same time.
Really annoying. Any thoughts about that?
