Short description of error
I can not use the color picker while I am texture painting, because of some bug that I can't run. I tried 2.8 and 2.81 but it's still there.
When I press S to select color picker, it manages to change mouse cursor as c.picker. But it can't pick any color. And the most annoying thing is, cursor stucks with the c.picker and doesn't change anything neither if I left click nor right click or ESC to cancel.
Is there anyone who can understand the situation? As you can imagine it's so hard to work with texture paiting without eyedropper tool!
