Visual bug - help please
Rather frequently these days I get a visual bug I would call "Exploding black bubbles". Wherever something related to lighting is happening these bubbles would appear around it and flicker with rather high frequency. Once it starts to happen it does not go away and I have to restart Ashes.
Windows 7 64 bit, i5 2500k, radeon r9 270, 16 gb ddr3 is my config. I have ashes configured at low settings.
Any suggestions what causes the problem and how to fix/avoid would be appreciated.
