Problem Description
Tilemap displays incorrectly when not in 100% zoom mode.

Attach a Capx

EDIT: I put it in a ZIP file so Google Drive doesn't try to just display its contents by default.

Description of Capx
A blank Capx except for a tilemap that should be displaying incorrectly as soon as it loads.

Steps to Reproduce Bug
  • Make a tilemap object.
  • Change the editor zoom.

Observed Result
It displays incorrectly, such as showing the top row of pixels from the tiles directly below each tile.

Expected Result
It should only be showing the tiles and not additional graphics.

Affected Browsers

Operating System and Service Pack
Windows 10 Home

This is another seam issue due to using linear sampling and the tiles blending some of the adjacent pixels from the tilemap.

Technically it is wrong but it's pretty difficult to fix (the editor uses a different, simpler rendering algorithm to the runtime) and it doesn't affect the runtime which is where it really matters. And you can work around it by using point sampling. So closing as won't fix.
