I have around 140 elements connected to the comp node and everything hangs as soon as I connect 141th one. If i re-route everything, using the second comp (to put strain off the node), everything is fine.

This might be a hardware issues - reading through the documentation on writing a GLSL TOP (TOPs are mostly GLSL under the hood) you’ll see:

Might be worth doing some digging to see if this could be hardware related.
The composite should splits up work based on GPU hardware so it shouldn’t be a hardware issue.
RA, can you share a sample. toe file where you make this happen? What resolution images are you using, what composite operation are you doing?
