Thank you for taking the time to update the diff. I should probably try it. I have noticed that if I am doing a lot of NFS I/O or rsync transfers to an NFS share that the pointer gets jumpy. The machine I am seeing this on is a Supermicro X10SAE with Xeon E3 1275 v3, 32GB of memory, and a Samsung 950 Pro NVMe SSD. I typically also have Firefox and Iridium also running with a number of tabs. It is using Intel graphics and running a 4K display which might be part of it. It seems to be better for me with efifb(4) and wsfb(4) on my ThinkPad X1 Carbon 4th Gen (which has the 2560x1440 display). I also tried the modesetting driver on my desktop which seemed to be every so slightly improved over the intel(4) driver but that is hard to quantify exactly. Bryan
