3.1.0 - low-proof Plots (WSL) generated using --disk16

[jiongxuan]

Hi, in the last issue(#439 ), I was using UBuntu 22.04 (real system). Then I changed a computer and used Windows 11 (WSL2 Ubuntu 22.04) and GPU drawing to generate compressed Plot, disk 16 mode, and the compression level was C1 .

Compared with directly using UBuntu 22.04, using WSL2 to Plots, the "invalid proof ratio" has decreased, but is still around 24%.

The reason for switching to WSL2 is to eliminate errors without modifying the parameters (BBCU_BUCKET_COUNT) mentioned in #276 . But so far, the effect is not ideal.

Please help me find out what is the reason and how to solve it. Thanks!

My hardware:

GPU: NVidia 2060 Desktop (6Gib vram)
RAM: 22 Gib
SSD: NVMe 1T
System: Windows 11 (WSL2 - Ubuntu 22.04)
Cuda: 12.1

well, proof rate - pure random. With wsl I saw 4/30 PR and 32/30.
But always have some numbers of PFF and PVF
