I saw in the release notes that Tonga support has been added, so I tried the latest version (0.5.2) with a Tonga card (r9 380 4GB) but get the following error on startup:
Failed to initialise device idx 3 (-13)
Is this card supported? Or is extra config required for Tonga?

I have the same issue on all CN algos except turtlecoin when I launch TRM while any web browser is opened (be Firefox, brave, Edge).
I get this error on a linux box with no GUI.
You are probably getting that error because your browser(s) are using the GPU? Try turning off "hardware acceleration" in chrome/brave.
