Since some time part of the letters on the screens are very tiny. E.g. under Google the first blue line is normal, the link line in green too but the additional lines under it (in black) is very tiny. Also on my bank screen, the page texts are normal by the lines with my payment information is tiny. And when I fill in forms, e.g. to buy an article online, the formtext is normal but the text I type is tiny. How can I solve that? Control + makes all text bigger, also when I set zooming on text only. So that is no solution
