This issue is occurring with my Samsung Galaxy S6 and a friend's Galaxy Note 5.
Textures from auto-tiles in tilesets are blurred and somewhat distorted. Also lines are appearing next to many tiles and objects (probably from objects next to that object in the image file):
Look at the walls closely. You'll see that they look oddly blurred and distorted. Above the sinks you can see white lines as well.
The graphics appear perfectly fine on identical PC deployments. They also do not occur on identical deployments to my Alcatel Pixie Theatre phone or Galaxy S7. Also worth noting that the RPGMV Benchmark tool on the Play Store, which was deployed with XDK more than a year ago, also did NOT have graphic issues on my Galaxy S6.
This is only occurring with tileset objects. Sprites, monsters, etc. are completely unaffected.
I tried playing with many different settings, such as the game's resolution, webGL/canvas mode, and doing a completely blank project with no plugins--the blank project also has the same issue.
This doesn't seem to be a game breaking issue, however it is very noticeable and somewhat distracting.
I am using
Xilefian's Webview deployment. According to him, this may be an issue with textures/mipmapping that he's seen on other games on samsung devices. I would try the default deployment method but it stopped working for me a long time ago.
