The ARCO has a similar issue, white flickering in the black line just to the right of the center. Occurs since the new 3D scopes technology was introduced.

Hello and thank you for your feedback.

I was unable to reproduce this issue on RC. Could you please provide more info? Thank you very much.

I'm also unable to reproduce that issue currently. However, I'll report back, if this occurs again during real gameplay.

I also experienced this issue when testing the RCO sight on the latest RC. The zeroing bars flicker depending on how you move the sight and will in some angles appear invisible. See my screenshot.

I used the following graphics settings:
sampling 100%
1152x648
16x9 - wide
Normal interface size

It gets a little bit better with FSAA and PPAA. The screenshot was taking with both Disabled.

Tried to confirm with others online playing the RC but some guy "YesYoa" just harassed me and became really rude telling me to Alt+F4. How did I manage that? I told him off but I don't think the understood the emotional damage he induced in me. Hopefully it got reciprocal in the end.

According to the ticket author that issue got resolved.
