My VT60 is a disaster when it comes to this shit. Even with pixel orbiter and me running the white screen wipe bar often for hours at a time or overnight after playing, I've got significant burn-in in the lower-left corner of the screen from playing Splatoon, where the words "Come on!" display. I had something similar from Shovel Knight, but eventually went away after a huge stretch of time. Splatoon's doesn't seem to be going away.
This TV is SUPER-susceptible to IR overall though. When I first turn it on I have to "warm it up" for a few minutes with the screen wipe, because on a cold-boot it'll get IR from the no-signal or Vierra logo literally after SECONDS. Often times after ONE second. The screen wipe will nuke the IR after a minute or two and then it's more resistant for the remainder of the time it's powered on, but it really makes me think there's something wrong with my specific set.
I am honestly horrified to play Mario Maker on it, that game is all about static HUD shit. Xenoblade X ain't gonna be pretty, either. It gets me pretty down sometimes, I bought the set used after they were discontinued for a premium cause it was Panasonic's last plasma hurrah, and here I am stuck with something that's actively hostile to gaming, which I do on it more than anything. I've got a V10 from way back downstairs that has a channel logo burned in the corner from a long time ago but these days it's basically invincible, I couldn't get IR on that set if I tried. I can only hope the VT60 one day becomes bulletproof from aging the same way.
