    Description

      The app is crashing in gl::GLContextEGL::Initialize()

      I see such crashes among users crash reports on AppCenter.
      It's not reproduced for me locally, but probably it's crashing on some specific GPUs or
      with some specific video drivers (with insufficient GL support)

      Stack trace:
