IMHO=2E I guess I'll have to have a look at getting the white/high-intensity-white behavior back=2E A *massive* thanks for all the insight, Andy! --Chris >=20 >=20 >=20 > RIP >=20 >=20 > https://photos=2Eapp=2Egoo=2Egl/YiVmFtWiK8Niy3Fw6 >=20 >=20 > -andyf >=20 >=20 > _______________________________________________ > freebsd-stable@freebsd=2Eorg mailing list > https://lists=2Efreebsd=2Eorg/mailman/listinfo/freebsd-stable > To unsubscribe, send any mail to "freebsd-stable-unsubscribe@freebsd=2Eorg"
