Oh, that's because Gaming X cards come with factory OC.
I was just thinking, if you were on 17.7.1 that may be pre-wattman. You may have been stable at default. If your card is a factory overclock then you likely fall in the same camp as many of us and NEED TO NOW MAX YOUR POWER LIMIT SLIDER in Wattman. Slide it all the way to it's max. Likely +25 - +50 depending on model. See if that doesn't help.
It doesn't. And the driver that I'm using (and don't have the problems) is 17.10.3, and it does have WattMan.
The big issues in Wattman began with 12.10.1. You mentioned you were on 17.7.1 previously and that it was fine. Sorry for MY? confusion. You also said before your card was a factory OC. Either way not sure what you have. If you are not maxing the power limit this is the common stability fix for RX series, polaris cards. Try it if you have not. You need to restart, should mention on Windows 10 you need to disable fast startup. Even if you change it in Radeon Setting this setting can be cached by fast startup and not work until disabled.
I have the same card and have experienced the exact same problems. Version 12.2.2 is so bad that about 50% of the time nothing comes up on my screens when I turn the computer on. I also updated the bios of the MSI card to the latest version and maxed the power in Wattman.
Since the day I bought the card, I had a problem where one of my two screens would go black and then come back. It was annoying but not too bad. I honestly thought it was the screen not the graphics card. Lately, with each new firmware update, the problem got worse. At one point, both screens would go black. Then both screens would go black and the windows would be resized when it came back. Then on 12.2.2 (and possible a few earlier versions), the screens wouldn't even come on about half the time when I started my computer or tried to wake it from sleep. This is when it got serious enough for me to put significant effort into figuring out what is going on, which is why I'm here.
I'm now in the process of rolling back the driver until I can find the latest one that only causes the screen to turn black without resizing the windows. That is at least a usable situation, although not ideal.
I don't use my computer for gaming. I use it for work, which is mainly writing documents in Word and using Chrome.
I use the card to power two 40" 4k Samsung TVs (Model: UN40KU6290FXZA)

The same identical issue with my MSI RX 480 8 GB gaming X. Tried all official versions of bios. The issue is not reproduced on 17.10.3(and below) and in these cases:
1. if downgrade power limit slider to -35% and below...the power/gpu curve is stable but decreased.
2. In global settings Frame Rate Traget control should be 55 fps and below.
3. Enable Vertical Sync in game(in most cases helps but not always)
There are no freezes in games in these cases .
