Using 18.12.3, after installing my new RX 590 Red Devil gpu, I went into Eyefinity looking forward to setting up my 3 monitors (one central large, 2 side smaller) but once again (this happened a year or so ago as well) I cannot get into Advanced settings to tweak the display of taskbar and bezel compensation. This is so annoying - it seems to happen every other driver upgrade.
You click on Advanced settings, the loading circle animation appears for a second or two and then absolutely nothing happens.
I haven't actually tried to use eyefinity much in the last 8 months so I don't know if this is a problem with 18.12.3 only, but if anyone knows the last driver version that worked properly with Eyefinity, I'd love to know.
Otherwise I guess I will just have to wait until an upgrade comes along to fix it.
