Hi,
I’ve come across a weird issue with SDL_SetWindowIcon(). I am creating a surface from pixel data that I already have available, using SDL_CreateRGBSurfaceWithFormatFrom(). I know that the pixel data is correct because I’m rendering it in my game, and I know the surface I’m creating from it for the icon is valid because I tried saving it to a BMP and the image was created perfectly.
But when I pass the same surface to SDL_SetWindowIcon(), I get a garbled mess.
I can upload some images showing what it looks like if there’s some way to do that in this forum.
Has anyone had a similar issue before?------------------------

Does it happen if you load the icon from the BMP that you saved?
Can you please report this on bugzilla.libsdl.org, and attach whatever we
need to be able to reproduce the problem? Also, please include what
operating system and version you’re running.
Thanks!On Mon, Jan 9, 2017 at 2:56 PM, dandago wrote:

It works fine when loaded from a BMP.
I’m using Windows 10.
The image data I’m using is proprietary, but ultimately I’m converting it to ARGB8888 format. I’ll see if I can make a repro project with some handmade image, but it will take a bit of time.

Okay, thanks!
Offhand I’m guessing that there’s an assumption about the pitch of the
image, but a repro case would be great.On Tue, Jan 10, 2017 at 9:35 AM, dandago wrote:
