not sure if its rr's fault, but its the most obvious victim :/

when looking at a relocator network without a cache in view, everything is fine

when a cache is in rendered view, all sorts of weird stuff starts happening

relocators go opaque, and traversing items are rendered as a square (at right edge of 2nd pic)

disabled all texturepacks to see if that helped/fixed, it didnt
installed optifine, didnt help
only thing that seems to fix it is not to use caches, but 640k item storage in 1 block? must have it lol

can provide modlist etc if needed

(ignore the noobiness of build lol.. in middle of changing storage/expanding base)

I can't seem to be able to reproduce this in my development environment. Could you post the version number of CoFH Core and Thermal Expansion?

EDIT: it might depend on the item in the cache. Could you post that as well?

ok has to be something about adding mods after worldgen
tried same setup on a newly generated test world, no issues

sigh .. so its my fault lol

most recent te/tf/cofh afaik..
pic of my mods folder:

thinking more on this issue, didnt notice happening til after i had added quarry+, remain in motion & project red (i know rim is buggy and has caused ctd a few times )

in the pictures shown earlier, the far caches by beacon beam have ic2 uranium ore, and the closer resonant caches (under chatbox) have ingots (red alloy, vanilla mc, and te types)

beats me wtf is the root cause .. at least its just a visual derp and not interfering with critical functions ;)

edit: btw, version checker is frikin sweet ;)

I got this same thing to happen when holding items from JABBA, but it isn't consistent. This needs more investigation.

It would be nice if I could reproduce this consistently :(

yes, this is very inconsistent..
switched from te4 caches to jabba barrels so it mostly doesnt happen anymore, but noticed it happen yesterday when a sorting alchemical chest went thru system
overlays on caches/barrels also flickered/didnt display properly when this was happening
weird

sigh

It's modders forgetting to cleanup after messing with GL states.
