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

Expected Result

Solid black, no seams between sprites.

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

Affected Browsers

Internet Explorer 11.0.17

Other browsers are OK.

Operating System and Service Pack

Win 8.1 64bit

Construct 2 Version ID

v200 (64bit)

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.

OK, thanks for the explanation!
