This is on gui-wm/sway-1.8.1, dev-qt/qtcore-5.15.12-r1, sci-libs/opencascade-7.6.3-r2, media-libs/coin-{4.0.0,4.0.2}
Compiling opencascade with gles2 didn't appear to affect this; surprisingly, setting COIN_GL_NO_CURRENT_CONTEXT_CHECK=1 didn't work on my first check on 0.20.2-r1, but did work when I tested on 0.21.2-r1. So I guess this does work. My first build also error'd when it couldn't find dev-libs/c-blosc, but when I uninstalled that later and rebuild stuff, nothing complained. This stuff appears annoyingly brittle...
