(from Sancho_10 and more but I don’t find it - no search in forums ...)
Zoom is much better now, but the “jumping circuit” is still bad.
The cause is the 0/0 fixed to “top left” and there is another issue that I can’t describe, it simply jumps.
- One more thing: The “Grid” (dots) are also “zoomed” at 75% and 150%.
