I looked at these two recently completed WU:
https://sech.me/boinc/Amicable/workunit.php?wuid=13407446
https://sech.me/boinc/Amicable/workunit.php?wuid=13407136
https://sech.me/boinc/Amicable/workunit.php?wuid=13403818

My computer is the one spending an order of magnitude more CPU time on them. The last one and I have the same video card.

I'm guessing it could be a Windows vs Linux bug? (Although mine shows NVIDIA GeForce GTX 1050 (1977MB) driver: 440.64 OpenCL: 1.2 vs theirs NVIDIA GeForce GTX 1050 (2048MB) driver: 442.19 OpenCL: 1.2)

I have Kernel size for NVIDIA GPUs set 16 but definitely still get UI lags when it's using GPU (but quite randomly likely related to it using the CPU at lot).

Oops.. looks like having it set at 16 makes it not work as well. Changing it to 19 or 20 helped, but brought machine to a crawl.
