I am sorry but that's beyond my reach as I am using node-webkit and if it doesn't support your GPU there isn't much I can do about it :(
Is there anyway I could just get the current version compiled with the latest release of the node-webkit? I've been waiting for 127 days. I would just use it in the browser since it works fore me there but it looks like you have to be a patreon member to unlock all the export options. EDIT: I just saw that you unlocked the online editor for another user having the same problem. Is there anyway you could show me some love too?
