White border around transparent pngs
« on: May 21, 2020, 06:21:39 PM »
I've noticed in the newer Retropie Builds of Attract mode that some of my transparent .pngs now have borders.  I double checked the same .pngs on my Windows build and they dont appear.  I also checked to see if there was infact any white or colored pixels around the border of the images in question.  They dont exist but for some reason I'm getting this border artifact in Attract Mode now on my Raspberry Pi. 

Further testing reveals that lower resolution wheel images are more likely to get this artifact.  So perhaps its related to how Attract Mode handles image scaling.

Can confirm I'm having the same issue...A faint border around transparent PNGs (see attached pic).
Any clue?

I have the same issue but haven't been able to figure it out.  I posted on it awhile back - http://forum.attractmode.org/index.php?topic=2944.msg20519#msg20519

Getting some help on the discord...At least a workaround is available.
I'm testing more based on the suggestions there and will report back.

A guide would be much appreciated as that Github link is vague at best about the process.
