I tried now with 'linux-generic' package (provides currently linux-image-5.0.0-20-generic). I did not experience any mouse lag issues, upon any successful* boot. So in that sense this is 0/10 reproducible with 'generic' kernel variant.

With 'lowlatency' kernel the mouse lag issue is roughly 5/10.

*) NOTE: with 'generic'-kernel I saw i2c-2 device NAK errors at startup boot messages, and sometimes the boot froze at that point. I checked with the 'i2cdetect' tool and the listing for device 2 showed "nvkm". Howwever, I saw the i2c-2 NAK errors during successful boots as well.

With 'lowlatency' kernel I did not see the i2c NAK-errors at all, but the dmesg in mouse lag case shows "nvkm" in it...

So, could this be related to KMS somehow?
