EDIT: See @AnimePhantasm comment below! My friend called the election board and they confirmed what @AnimePhantasm and @fmstrat commented! This was Virginia reusing last year’s envelopes.
OP I am an absentee voter in Blacksburg just next door. Shine a light on the blacked out part. I am 99% sure this is legit, they just crossed out the witness requirement. I can see the word witness under the sharpie in your picture. Virgina doesnt have to do that witness thing anymore. We did at the last general election, so I am guessing they just reused the same envelopes. You should call and ask your elections office before alerting the news. They are hardworking folks whose jobs are already 100 times harder then they used to be. Stirring up reports of election fraud where it isn't happening makes us just as bad as them.
Yea, as the other person mentioned, to my knowledge (which is limited) the video decoding in the browser on Linux tends to be browser and hardware specific. I know it’s gotten easier over the past couple years tho.
