[Bug 105530] Stuttering on Raven Ridge when TearFree is on

--- Comment #11 from Andrew Sheldon <asheldon55 at gmail.com> ---
I've run some tests using:
https://testufo.com/photo#photo=quebec.jpg&pps=960&pursuit=0&height=0

I've found that with TearFree enabled, there is a stutter every 4-5 seconds.
This occurs at different refresh rates (60hz and 92hz tested). If I turn
TearFree off, no stutter or tearing occurs (the test uses v-sync).

I suspect the bug is related to #106175, since if I turn compton on, the
stuttering becomes severe. So perhaps there is some underlying issue that
affects both TearFree and compositing managers, but not regular v-sync.
