Greetings, fellow Handmade Hero hackers!

I've been looking at many of Casey's videos for a while, and recently decided to start working on the actual coding. Because I use Linux, I've been following the SDL2 tutorials, and, out of curiousity, recently decided to see how the recent code runs.

I've cloned the sdl repository, copied the cpp and data folders to the right places, patched the patch file, ran the scripts and this is the odd result I get:

Any idea what could be causing this? Thanks in advance! :)

I doubt this is a problem with SDL2 because it appears you are missing the handmade hero assets. Make sure you have placed the assets in the right directory that the game looks in for them.

I don't think this is asset problem, because you can see P and C letters in the screenshot. And the sizes of characters looks correct.

It more looks like problem with multi threaded texture download. Casey is getting exactly same problem on the stream from time to time.

Well, it was worth a shot. I can't help you because I'm not on a Linux machine. Good luck anyways :P

Thanks for the info, mmozeiko. Which streams has he experienced the problem on so far? Does he have an idea of what the problem could be?

The problem is that multi-threaded shared OpenGL contexts simply doesn't work. Casey has said that it should be removed or changed (to PBO).

Yeah, I'm pretty sure we have to ditch multi-context downloading. nVidia's materials gave us the bum steer on this one :(

Any idea why it doesn't work properly? Is it a problem specifically on Nvidia cards? What about Intel or AMD?

How can the multi-context downloading be turned off? I've been playing around with the #if preprocessor blocks in sdl_render.cpp to no avail...
