Draw-manager mutex has to be set before activating OpenGL/GPU context. Otherwise, parallel jobs (like preview rendering) may try to activate the context from another thread. Also: Use WM wrappers for activating/releasing OpenGL context, which have an additional assert check. Suggest to backport this for 2.83.1.
