SFML crash on Galaxy S22

Subject of the issue

So this gets quite complicated but here is what I got.
While testing I found that for some unknown reason the SFML 2 app crashes on the Samsung galaxy S22. Since I've previously tested the same code on a dozen different devices from different manufacturers, it was quite weird. Well, it seems to crash in the window.draw() function no matter what you ask it to draw. I've tested another app that just clears the screen to a specific color and doesn't draw anything and it works without any issues.
I've captured the call stack of the crash:

as well as the specific line that it crashed on:

My conclusion:

It seems like the galaxy S22 series has a completely new GPU compared to literally any other smartphone.
The Xclipse 920 that it has is the only Xclipse GPU ever. The now new s23 series no longer has this Xclipse GPU.
So I guess it could be a graphics driver issue. Or something similar. I haven't tried just removing this line that the program crashes on as I'm unsure what it does exactly.

Your environment

Android Studio 2022.1.1 on Windows 10
SFML 2.6.x branch
Used CMake, Ninja, Android NDK 25

After analyzing this issue further, it seems like the S22 indeed does not have this extension glBlendEquation (or at least not when using GLES 1.0) resulting in a crash. Simply changing the else { ... } to else if (GLEXT_glBlendEquation) { ... } should be a fix. I'll make a pull request soon.

Just an interesting observation, after "upgrading" SFML to use GLES 2, all of the issues are gone.
