Problem fixed by running Windows key -> Compositor -> Re-enable.... So issue fixed, but it could have been so nice with a more visible notification about effects being disabled possibly because of driver error and that one could try to reenable... here. So this turned into a feature request from a bug. Thanks for the help :-)
