Yeah exactly, I can look past when it happens on like menus and such (even the black bar across big green area of my XB1 dashboard) but it's happening more and more in "normal" viewing of shows and games. Like watching Star Trek Into Darkness blue right, the part where Uhura talks to the Klingons (spoilers!) there's a couple parts when the subtitles pop up there are 3 large bars that go across her face! Just terrible. It "could" get better with time, but if not, then I've missed my return window and stuck with a TV (its financed) that annoys me nearly every time I use it.
The lengthy return window is why I chose to go with the S64 at Sam's Club. Those are difficult to find now though. Best Buy's return policy is 7 or 14 days, if I recall correctly. Anyway, if it bothers you a lot you probably should go with the LCD. All plasmas suffer from line bleeding, even the high-end expensive models that are rated as having the best picture quality.
