EVF vertical stripe

[Chosei Funahara]

I can't find any thread for EVF's behavior.
It happens, when it boot it up.
Just EVF shows white vertical stripe for a while and when I change EVF's set ups, goes away. Is that normal? (not show up on LCD, only EVF)
Please let me know.

EVF Vertical line

R1 came back from Lake Forrest for audio board upgrade, my EVF acts different, I had this problem, and now, it's constant vertical white line appears, after 10 minutes latter, it disappears.
But if i shut down the camera, again when I start boot up the camera, this vertical line appears.
does anyone have same experience?
