Comment 10 for bug 1924251

@seb128 interesting, I've just tried this on a fully updated jammy image on a Pi 400 and /usr/lib/aarch64-linux-gnu/webkit2gtk-4.0/MiniBrowser starts quite happily; browser window opens and ... nothing but blank white space within the body of the window. All the controls in the toolbar are fine and it's definitely able to navigate to pages, and after a bit of experimentation I'm reasonably convinced it's all "working correctly" with the one exception that nothing actually shows up (but the mouse cursor changes shape in all the right places, etc).

@vanvugt: in case it's of any use, MiniBrowser produced the following console output:

** (MiniBrowser:149058): WARNING **: 21:30:51.512: GDK is not able to create a GL context, falling back to glReadPixels (slow!): Unable to create a GL context
Cannot create EGL context: invalid display (last error: EGL_SUCCESS)
