Hmm.... That's definitely important information, thank you for testing that! Haven't had the chance to roll back to 1.03 on mine.
Guess they broke something in the scripts and display controller remains stuck partially on somehow.

Between 1.03 and 1.04 only app was changed. Scripts remained unchanged.
vano:
I switched the oscilloscope to sleep mode several times, from 30 minutes to 2 hours, no stains, everything is fine.
AndyBig:
I also had the oscilloscope in standby mode for up to a day and there were no problems with the display.
Moduvator:
Quite frustrating indeed! I was able to reproduce it again over the weekend, even though this was now a vertical strip of brighter pixels in the right part of the screen.
The scope then worked fine today over one several hours long sleep cycle after a fresh boot, however when coming out of sleep a second time that strip has reappeared. Moreover, I was also been able to spot a very faint RIGOL logo imprinted, as if that was the last frame sent to the LCD as it shut down but pixels got stuck under constant voltage.
Can't work out the pattern so far but this does seem to require a few sleep and wake up cycles to trigger, might not work on the first one!
