After several months, I went again to Kicad to check some old PCB before to etch them.
Honestly I don’t remember well, but allegedly before…to drop Kicad last time I updated the version (currently my version is 5.1.2 (Win 7/64)).
Well, as I open a project and load a schematic, I get a popup in order to remap the symbols, quoting a non compatibility with previous versions once remapped.
Ok, no matter, I do it.
When the schematic opens (with no changes, as I can remember), I notice a grey background and no frame with the schematic info anymore… Zooming out, I realized a giant grey dot sorrounding my schematic…
I tried to eliminate the grey through the settings menu (background, etc), but no way.
There is any reason for that giant grey dot and how to fix it?
