Zooming on Large PCB's (Bug?)

For answering this question:


… I did a little experiment.

I made some selection in an existing PCB and moved that 1000mm to the right. Then I could not zoom in anymore on that moved section.

In this post, Rene wrote PCB coordinates are 32 bit integers and should go from -2148 to +2147mm

Python says:
>>> pow (2, 31)
2147483648.0

Bobc added that “Weird stuff” starts to happen once you go over a meter. An experiment confirms I can not zoom in on a 1206 resistor if it’s X-coordinate is larger then about 1074mm, which is suspiciously close to half of the 2147 max coordinate.

So how important is this considered to be?
@smart1 Did you encounter further problems with your big PCB?

Mike Harrison (Mikes Electric Stuff) makes big PCB’s also, I remember one of his youtube video’s where he talks about having difficulty in finding a PCB manufacturer (in the UK) that could make his PCB’s. I thing those PCB’s were also over 2 meters long.

KiCad version? Have you tried with 5.99?
