Sprite Seams are visible on Windows 8.1
Sprites that are next to each other show a transparent seam on Windows 8.1, and in Internet Explorer 11

Attach a Capx

Description of Capx
Displays 64x64 black sprites next to each other on a white background.

Steps to Reproduce Bug
1. Preview in Internet Explorer 11

2. Also appears in a Universal Windows Store Export to Windows 8.1 ( since it's using the IE browser engine I suppose)
  • Export as a Universal Windows Store, Universal 8.1
  • Open the .sln file in Visial Studio (I am using VS2014, update 4)
  • Create a test cert, and run

Observed Result
White background is visible at the sprite edges

I've tried all the export/preview options to no avail, it seems to be an IE problem..

Other browsers are OK.

Closing as not a bug. Seams may appear between exactly adjacent objects when you use floating point positioning or scaling. Since you use "letterbox scale" here you will very likely get floating point scaling. To guarantee seamless rendering you need to use letterbox integer scale, point sampling and pixel rounding. Or just use the Tilemap object and enable seamless mode.
