MCPE-24731[Resolved] Redstone rendering stutter
(This issue has existed since the first Beta build, but I didn't report it.)
Redstone dust, repeaters, and torches, and probably comparators (i.e. all components that show powered/unpowered state visually) are not rendered smoothly and continuously. In the video is a simple clock set to switch states every 5 RS ticks. When I look at it, the components all flash as expected for 3 seconds, then behave erratically for 3 seconds. The appearance in the erratic state varies from one cycle to the next. Sometimes two adjacent pieces of redstone dust will freeze with one of them lit and the other dark. (You can see it in the video just above the repeater in the clock.) Sometimes the erratic behavior ends with a rapid succession of updates as if the renderer were rushing to catch up.
This is a rendering problem only, it doesn't affect the internal states. As evidence:
- If I attach an empty dropper to the clock, it clicks precisely once per second without interruption, even while it appears to be unpowered..
- If I use the clock to power a redstone torch that disables a hopper under a filled chest, the hopper pulls items from the chest at a perfectly regular rate, including while the torch appears to be disabling it.
- I have seen redstone particles emitted by dust that appears to be unlit.
Positioning myself so that I can only see a single redstone component has no effect on the stutter.
I observed the problem with Task Manager running. There is no noticeable correlation with CPU utilization, disk utilization, or network utilization. Memory utilization is flat.
This problem makes debugging redstone devices much more difficult because it's hard to determine whether a component is behaving the way you expected it to when half the time it appears to be behaving erratically anyway for a completely different reason.
