I just discovered something that was not readily apparent to me before as a symptom of this bug: it is not just the mouse feeling laggy, but mouse movements actually *cause* frame drops in other applications.
...I get okay-ish performance if not touching anything, but whenever I move the mouse cursor over it, frame drops significantly. Demonstration of the issue: https://youtu.be/DUV0vRGFIBU
This was tested on a clean startup with no other applications running. This might be a useful test case for anyone coding towards a solution here.

For example, if I run Geeks3D's GPU test "furmark" (available from http:// www.phoronix- test-suite. com/benchmark- files/GpuTest_ Linux_x64_ 0.7.0.zip ) like this:
DISPLAY=:0 ./GpuTest /test=fur /fullscreen
