Don't know where these libpng warnings are come from.
I have both librarys on my system.

Any Idea?
How can I help to debug this?

Have you tryed downgrading your libpng to v1.5.5?

 

I think, I have the same problem. But I am not sure, if downgrading the library is the best way to fix this.

 

I was having the same problem with juxta in my windows standalone laucher.

https://forum.kag2d.com/threads/most-recent-update-has-broken-standalone-launcher.19660/

 

Does this still happen on this build? Is this through steam? Or a standalone? Have you tried reinstalling?

 

I an trying it today. Fingers crossed.

 

@Duplolas @DasLeo Is it still happening?

 

Yes. It may be the school's new security policy.

https://forum.kag2d.com/threads/duplo-hacks-his-school-network-and-becomes-admin.20208/

When I went through the stuff on there, they implemented a few new security measures. Only thing is I can still download the latest updates and can still get on other servers for different games.

 

Fixed: KAG now has a rungame.sh script for a while, bundling the libpng dependency correctly.
