<span class="quote">> The stuttering is caused by enabling TearFree via xrandr.

Since HW cursor updates are always supposed to work without delay, and there is
no sign of an issue in the attached userspace information, this seems like a
kernel (DC?) issue.
In the amd-gfx mailing list thread, you said that this started on 2018-03-07.
Is that just when you enabled TearFree for the first time, or did this actually
not happen with older kernels?</pre>
