If this has been suggested sorry, I couldn't find ticket to update it to show you that it is still happening.

Made this in 1.13 and now after awhile of on and off, ghost blocks will appear that could easily break other things. To recreate make a simple redstone project or something that abuses fast redstone mechanics and flip lever on/off repeatedly.
