@Evgeni_Popov btw, I noticed in this lastest chrome update, the uniform analysis requirement has been turned on. I found some places in my code where the conditional texture map sampling was being done, and moved all texture sampling outside of the conditionals. The warnings are gone and it runs as normal.
What I still can’t figure out is the root cause behind those bumps I mentioned here. It’s not a problem being caused by non-uniform operations on the GPU, which means the same GPU operations and draw calls are happening on the m1 mac, my pre-m1 mac, and a windows machine, but the way that those operations are getting executed is somehow different on the m1’s hardware & drivers.
