Running SDL in the OverlayDisp applet context

[exelix11]

I'm working on a custom OverlayDisp replacement app. It's the applet that renders the quick action menu (when you long press home), the notifications and the power menu.
I've succesfully managed to get a framebuffer that hos overlays on the running title using the vi service and now i'd like to use SDL for the hardware acceleration.
I've already implemented the code to set the viDisplay and viLayer fields as overlay without having to edit the source but when testing i discovered that SDL_CreateWindow fails with Could not initialize EGL.
This error is thrown here when eglInitialize fails (the function pointer is set here).
Note that this happens before i try to edit the driver data of SDL, the code looks like this:

if (SDL_Init(SDL_INIT_VIDEO) < 0)
	SDLLOG(1)	
sdl_win = SDL_CreateWindow("sdl2_gles2", 0, 0, 1280, 720, 0);
if (!sdl_win)
	SDLLOG(2)

To run my app i build the nsp and use it to replace the exefs of OverlayDisp with atmoshpere's layered fs.
I've also tried running the nro from the homebrew launcher and surprisingly that renders fine, obviously without overlaying.
At this point i'm not sure about what to do, is there some permission or system flag i'm overlooking ?
A thing i noticed is that the nso/nsp i get is ~4 Mb while the nro is around 9, could it be possible that some part of the opengl driver is left out ?
(I'm pretty sure this isn't related to SDL itself but the mesa repo doesn't have the issue tracker and i don't know whom to ask)

Can you join IRC EFNet #switchdev?

Yeah sure, just joined. I'm not too familiar with irc tho.

The problem was caused by the heap size, increasing will make opengl init normally.
