Chapter in this post:
My iMac is around 2 years old. Recently I've always had a problem after hibernation when I want to write something on Google. Then, after some delay, the letters come first, followed by small letters with different characters over them. I can only write correctly again after a restart.
My ideas went in the direction that maybe the graphics card is defective or no correct driver for the graphics card is installed. But with a 2 year old iMac there are seldom problems with drivers ... Likewise, a defective RAM module could possibly cause such phenomena, but then rarely always in the same place, but rather randomly scattered over everyday life. In short, I was a bit at a loss ...
After a short time, however, the reader returned and was able to solve the problem himself. He had received a tip in a forum that this phenomenon with the strange characters above the "normal" characters can occur when the mouse and trackpad are used together.
His comment on this: "You wouldn't have thought of that in life."… I see it the same way. ;-)
The problem seems to be limited to OS X El Capitan, by the way. If you use the current operating system and have two "mouse pointer input devices" such as trackpad and mouse active, you may also get such cryptic characters in the input field. It would be interesting to know whether it also happens when you use a mouse and a Wacom tablet, because this will certainly happen more often.
I can only say: Thank you, Heinz! Both for the extraordinary problem and for its solution! : D
