I'm trying to add support of HiDPI displays on web swf application. To achieve this, i used starling.supportHighResolutions and configured AssetManager to scaleFactor = 2 useMipMaps = true.
Atlas was packed with fresh version of TexturePacker (3.5.3) as ATF. I experimented with different «pixel formats» and «mipmap min size» options — but app handles an atlas only without useMipMaps = true. If this option is on, app throws this error:
[Fault] exception, information=Error: Error #3700: A texture sampler binds an incomplete texture. Make sure to upload(). All miplevels are required when mipmapping is enabled.
Mipmaps are needed to show 0.5-scaled textures on non-retina displays.
