Xaver says this warning from upstream code is harmless and can be ignored.

I'm not satisfied with this resolution. I have a high refresh rate monitor. Every time i drag a window around, on each refresh cycle, this log is spammed to the journal, causing unnecessary disk activity and wasting disk space with useless logs. I would like this log to be suppressed or throttled.

Seems to be fixed with 6.8.3 on Arch.

No, it does not get printed on every refresh cycle. And Nate wrote, this warning is not in our code. We cannot suppress it.
