So I just started noticing the corner of my left eye seems blurry when wearing the Rift. Iv'd had it about 7 months and this is the first time noticing it. Checked all cable and sensor alignment but think its a hardware issue. just a bit of the left lens corner is grey and shaped like and arch and the edge between the gray and screen color has a little flicker like the leds in the screen are flickering. Anyone else seen this?
