DisplayLink drivers have historically caused log spam on many occasions (or Apple's drivers have been pushed into buggy edge cases which spam the logs because of DisplayLink connections, perhaps).
The fix used to be creating an Apple System Log config module (a file in /etc/asl/) with the instruction to ignore any messages matching a pattern, as seen in the log itself, e.g.
Code:
? [= Sender WindowServer] [= Level Warning] [S= Message _CGXGLDisplayContextForDisplayDevice] claim only
If someone can figure out how to get those asl config modules running again in current macOS versions, that's the "permanent" fix.
In the meantime, you can run the following one-liner in Terminal to tell the log system to just drop all WindowServer logging. Do note this will have to be redone anytime you restart, log in, if the WindowServer crashes, etc.
Code:
sudo log config --process=$(pgrep WindowServer) --mode "level:off"
