Well I tried an opencl benchmark I found, and my computer has fuckied a major wucky… Edit: reboot fixed it but it seems opencl is super unstable on here. I ran hashcat again, this time with --force, and found that it did nothing, then there were weird colors, then plasmashell crashed. Luckily plasmashell has good crash handling and it was able to go back up so I could see that hashcat reported something about gpu hang being the reason for the crash.
