Touch reporting half coordinates in iOS retina displays?

SDL Development

Hi all,

I’m trying to get a program to run in both iphone retina mode and iPad. It’s pretty much working great except for the fact that in the iOS 5 Simulator for iPhone 4 in retina mode, touch location is halved for both the x and the y coordinates.
Does this happen to anybody else?

Thanks in advance for your time
Joseba

Thanks for your reply :slight_smile:

Hum. I’m not using the latest SDL HG code, but it’s pretty recent.

I’ll see if I can replicate the issue with the latest SDL code.

If SDL is supposed to hide this or not and whether this is the actual source of your problem is beyond my knowledge, maybe someone else can tell more.

Regards,
Jonas Thiem
