If I am remembering correctly, John sees the flickering more so because of his field of work. He is more sensitive to that phenomenon.
v37 didn't have the issue - it was introduced in v38. A few people posted here that were able to see it, but yes, due to my video QC skills, it's easier to see for me. Also, the higher the brightness, the easier it is to see.
If anyone can't see it, but wants to know what it looks like, just look
through the camera on your phone, at the P3 screen. The scrolling you see on your phone is what we see without having to use the phone. It's the refresh rate of the screen. Not sure why ProVape changed it, but it affects all menus.
Note for ProVape - It seems the screen refresh rate is a pixel clock? The refresh speed is different depending on how many pixels are lit, as in going from screen to screen, menu to menu. It could also be brightness related (where 100% would be all pixels lit, and 50% where half the pixels are used in a menu, etc.).
Hope you guys figure it out. If not, I'm going to want to downgrade to v37 - hope that's possible.
