Shop lighting bug after ALT+TAB with Exclusive fullscreen/Replay take-over +Unable to use freecam in replays when paused.

There is a lighting issue with the shop that (as I believe) continuously clones the light source, which increases the performance impact and SIGNIFICANTLY lowers performance.
This issue is usually encountered every 3 pauses/replay take-overs (doesn't matter when I pause during the replay) and I didn't find any other solution except restarting the game/replay. This makes recording footage using the replay system extremely hard. This doesn't happen in matches because I use borderless window, but the fact this can happen in a first place is annoying.
I think this issue was present ever since the closed beta has started, I've seen it for a while but specifically now it became a problem for me (Yoshi please spare my devices, I don't want to smash them in anger because I'm trying to make a video).
The second issue related to replays is described in a title of this post. When paused, the player cannot move the camera which makes it hard to select specific angles for the footage.

Steps to Reproduce:
1. Load replay
2. Use timeline 3-6 times
3. ????
4. PROFITT!!1!!!

Notes
Severity: Low-Medium
Type: Performance
Repro Rate: i gonna krillmaself

I am glad I am not the only one who has experienced this issue. It can be recreated with just alt-tab in the sandbox, by facing away from the shop. It has the same behaviour of stacking up the lights but they will fade and disappear in about a second or two.

Here is the brightness it got to during the time it took me to write this post.
