I would blame Nouveau before your graphics card. Nvfx is known
to be problematic nowadays, before the rewrite is finished.
Also desktop OpenGL is different to GL ES 2.

It cannot cause your problems, but it is a workaround for a
Nouveau bug, where Nouveau ends up with a buffer setup the
hardware cannot support, hence triggering the assert.

Use --disable-setuid-install to configure, it should be shown
also in ./configure --help. Also, a recent patch makes setuid
step not fail the installation but continue.
