Hi Stan Did you find a solution. I am having the same problem, though with a fragment shader. The strange thing is that it only happens on one of my three iOS devices - the newest one. The code stops with the failure, but if I continue executing, the code runs fine, but the "Invalid device load executing fragment function" comes every frame. I cannot seem to debug my way through. Thanks in advance, Michael

THANK YOU Stan !! That was really helpful - to the degree that I actually found and fixed my problem. It turned out that I SOMETIMES had an index out of bounds, but only on certain devices and with certain resolutions, which I used your advice to track down. Cheers Michael

Did you ever find a solution to this? I am stuck with the same issue, where an incomplete ASCII sentence stalls the receiving client, and keep trying to pass the same data over and over again, until the connection is finally canceled. Any help or hint would be greatly appreciate!!

Same issue here
