Some computers would display a Shmeppy map with some strange grid lines. Like here’s a screenshot from my own computer:
Those faint horizontal gray lines are not there by design.
These lines might appear on your computer all the time, they might only appear some of the time, they might look like this screenshot, they might like quite different. Whatever the case, they’re kind of annoying.
I’m happy to say that I think I’ve vanquished these lines, and they shouldn’t appear for anyone. However, if you do see them, please let me know! This bug is very device-dependent and unfortunately I don’t have dozens of different machines at my disposal.
Happy shmepping :).
