[CC 1.76, MC 1.8] Computers turning black and not displaying any information even though they're still working

I'm currently running 3 computers and 2 turtles together, the turtles are managed by 2 of the 3 computers and the last one is to keep track of all the items in the system. The 3 computers started off with a working screen and showed their info but when I walk away roughly 50-80 blocks or so they were a constant black when I came back.

The computers are running in an infinite while loop and respond to the os.pullEventRaw method (one constant event is when a turtle moves that it sends it's location, rotation and fuel back to the manager and this forces the screen to be re-draw). They still work and the turtles keep doing what they need to do (and what the managers command them) but I just can't see any information on screen anymore.

Also the wireless routers on top of the managers appear in the off-state even though they're in use.

I do have a couple other mods installed but none that would interfere with ComputerCraft, all my installed mods are

CodeChickenCore-1.8-1.0.5.36-universal
ComputerCraft1.76
fastleafdecay-1.8-1.5
InventoryTweaks-1.59-176
ironchest-1.8-6.0.99.749-universal
MapWriter-1.8-2.2.11
NotEnoughItems-1.8-1.0.5.104-universal

And I'm running the recommended version of Forge for Minecraft 1.8 (1.8-forge1.8-11.14.4.1536) via the Minecraft Launcher, my Minecraft instance has 8Gb of RAM allocated and I'm using the default texture pack.

Also on a side bug, the turtles often appear in a different orientation then they really are if they've been standing still for a while, once I open a turtle it fixes itself though

Edit

I just restarted Minecraft instead of just closing and reloading the world and it appears to be working fine now, the bug may still pop up in the future though.

I can confirm this happens.

I am unable to create 100% sure way to replicate it but i believe its related to a tree growing from sapling to tree.

This don't happen in all setups but when a tree grows next to computer/turtle/monitor it causes this glitch.
Computers and turtles keep working correctly its just when accessed show nothing like in screenshots above.
Monitors seem to split into component screens shoving see-trught area in place of screen (some even change direction.)

Will post more if i am able to determine 100% reliable recreation method.

SideNote: By the fact that relogging/leaving and reentering world always fixes this i believe its semi-clientside issue?

It would be weird if it were to be related to tree's growing but that is the main purpose of one of the turtles (not the growing but the chopping of the tree's and it moves next to the saplings so they can easily grow right next to the turtle.

In my edit I said it was fixed by restarting MC and it is happening to me again right now, even to a computer not even turned on so your idea of different render layers may be true.

These points strongly suggest that the issue is related to these bugs, where quickly changing a decent amount of blocks within a chunk messes with computers / turtles / monitors.

The second one about the orientation is invalid for my case, I'm not using any kind of explosives, haven't even crafted them yet. The behaviour is the same though

The first one seems like the issue here and thus should be re-opened (I've made a comment on Github linking to this bug report)

Edit:

I've added a reproducible script and instruction to use it in the Github issue, works every time, hopefully Dan will be able to fix it

Explosives aren't the point; the two reports are hitting upon two different triggers for the exact same issue. ;)/>

Tree growth, explosives, the fill commands… I imagine you can see the common factor there.

Ohhh you think the rotation bug has to do with the same display issue bug, that could easily be the case yeah
