Vertical lines occur at randon

[LemaruX]

When running Pistorm with a Framethrower with latest videocore and Emu68 (as of now) you occasionally get vertical lines down the screen.

In my case I am on an A600, but Claude has confirmed he has also seen it on the 500.

No steps to replicate, as it happens totally at random.

Restarting the machine resolves it, but then it happens totally at random again

I've just seen this while booting. When I boot, there is a near-black-screen (the RGB black is always a bit very-dark-gray, and it shows correctly like that on the Framethrower screen) before the RTG kicks in and the Workbench appears. I had just that "black" screen with exactly those really-black lines over it. Then the switch to RTG happened and looked fine. I can't remember if I tried to switch to a Framethrower screen during that session or if I did a reset before that. That was the first and only time I've seen it so far, but I only built my FT last night, so that doesn't say much.

A500+, Classic PiStorm, Pi 3B+, Emu68 1.0.7, latest released FT firmware.
