Hi Daniel,

The fix for this issue not only requires xorg 1.21.1.4, but also a newer version of the Nvidia driver. We have confirmed that the combination that fixes this issue is (1) xorg 1.21.1.4 (from Kinetic) + (2) a development version of the Nvidia driver, which is under NDA.

To be honest, Nvidia is also a black box for us. We don't know the root cause of the lag or whether it affects only the Nvidia-525.
