Grid doesn´t work properly

[cristobasu]

I have a problem with the grid. Sometimes when i zoom in or out some lines dissapear for some reason.

I don´t know if this issue has something to do with my gpu or sometingh else.

You can test if it is the GPU Preview by switching to GPU: Ctrl E

Thanks! when i changed to cpu preview the grid worked properly. Is there any difference between gpu or cpu preview?

GPU Preview uses the processor from your graphics card to speed up the display.

It is faster but, as you have seen, sometimes less accurate than the CPU Preview.
