Sorry for the very long delay(work + testing your suggestions), but here are a couple of screen recordings, the first one is showing the responsiveness problem when opened for too long, also I you can see I'm using Ublock there, but I've tried removing each extensions that I was using and no combination would solve(or improve) the problem:

But I ended up with the same problem regardless of the combination, eventually I just went back to Ublock
*Showing the responsiveness problem:
Obs1: I made sure to record the mouse clicks, so you can see when I double click the topbar of orion to get it to fill the screen
Obs2: The screen capture is not lagging
And here's when I reseted Orion, just completely closing it and opening again:
Here I also make sure to record the mouse clicks, so you can see when I do the double click to full screen.
Also maybe it's worth bring up that in general my whole system has gotten more slow with Orion(I don't mean with the app installed, but as Orion gets less responsive, other apps get less responsive too) I'm trying to troubleshoot my system, but what makes me think that "it's Orions fault" is that when I close it things go back to beeing responsive.
I also keept the Activity Monitor open to see if there was a huge usage of CPU and/or RAM, but there wasn't, it was normal, CPU bellow 30%, and RAM around 12/13GB.
I'll post here any updates on troubleshooting.
