Hi there!
I have AMD APU A8-7600 with Radeon R7 graphics which is disabled by default in older version but after upgrading to 0.6-220@221221 and above, the integrated graphics is enabled. From changelog: “Built-in-CPU graphics now always the first in GPUs list.”
I think that’s the cause of TeamRedMiner won’t recognize the discrete GPUs.
Please disable the built in graphics or let users manually disable it.
