Similar problem with ssc337de + gc4653:

majestic[638]: Channel 2: 2400x1440@5fps

Screenshots are taken with a resolution of 2400x1440 instead of 2560x1440.

If I set JPEG resolution to 2560x1440 in Majestic > Settings > JPEG, I get an error message:

majestic[638]: Channel 2 invalid size: 2560x1440
