kawpow algo not working with Linux

[Khameleon21]

Have two installations of xmrig-mo on the same PC. One Win10 install and the other in Manjaro. When running in Manjaro, the miner selects kawpow as the most efficient algo to use (same in win), will connect to the server and get new jobs. The GPU is running full speed, but no shares are ever excepted. It will keep getting new jobs, but not one is accepted. When I run in Win10, it starts accepting shares almost immediately. If I remove kawpow from the .json file, other algo work fine in Manjaro.

Both Win, and Manjaro are using the same .json file (except when I remove reference to kawpow).

Any help would be appreciated. Please let me know if you require more information.

Thanks
