Two Page Spread - PDF Display Issue #140
Description
In Two Page Spread I've encountered an issue on only certain PDF's where a very faint thin black line will visually separate the left and right page in 2 Page Spread.
On some PDF's this is not the case, not sure what causes this. I've tested this on both PDF's with version 1.3 and 1.4 and the PDF version doesn't determine whether the issue happens or not.
By comparison when opening the PDF's in macOS's native Preview with 2 page spread, the thin gap line doesn't exist on any PDF and they are displayed seamlessly side by side.
Simple Comic is such a powerful, light and useful tool, that it has slowly replaced Preview for viewing any PDF and thought I'd bring this to attention.
