Description
This issue is only present on v1.3.1. Previous versions are not affected.
Tested with 5ms opus frames on an MIPS 74Kc V5.0 CPU.
Encoding times for opus_multistream_encode():
v1.3: 2.5 - 3ms
v1.3.1: 2.5 - 12ms
Let me know if you need anything to reproduce the issue.

Research direction
Start by comparing the v1.3 and v1.3.1 implementations and execution path of opus_multistream_encode(), then reproduce the reported 5 ms frame benchmark on an MIPS 74Kc V5.0 CPU. Done means identifying the v1.3.1 regression and confirming encoding times no longer reach the reported 12 ms range.
