It's a good idea to tell me how much % of shares are invalid, if it's <0.5% it's ok. If you want zero invalid shares - use "-the 2" option. If it does not help - something is wrong with your GPU.
100% of GPU 1 is invalid. Just did a test with a benchmark and there was a large amount of artefact. Must be device failure.
Just a suggestion but the remote manager really need a custom colour option. The White background is killing me. And if you do work on it please allow different text sizes as the font is crazy small on a 4K screen. Thanks for a great system though
