Vindicta's Assasinate main scope texture quad shows up later than the sides

[roughness.squared]

Haven't seen anyone report, so it could be the sun flares flipping bits on my gpu or something, but Vindicta's Ult when zooming in is missing the main scope part for around a second, while still showing the half transparent dark sides, and then it loads in and renders normally for the rest of the match. The resolution does not affect this in any way and restarting the match (in this case, quitting and starting the sandbox) makes the issue appear again for the first zoom in, but way less apparent and appearing way faster. Game is installed on SSD and there's nothing that could be related to this in the console.

Here's a video as well, loading the sandbox two times.
