Invalid segment pixels:: Protect virtuals segments from devices pixels count change

Quoting from discord thread https://discord.com/channels/469985374052286474/1210772751800074240/1210772837443440711

I noticed in the dev builds my own system generated such an error into sentry

Invalid segment pixels: (0, 91). Device 'breakme' valid pixels between (0, 57)
However, looking at the setup, the actual issue is that I have

Invalid segment pixels (0, 91) against virtual 'breakme' where the segment is mapped against device 'fake128' that is set to 58 pixels (0, 57)

This is the scenerio where device has its pixel count reduced, we don't yet proliferate that reduction in pixels into all the virtuals that reference it as a segment.
