On laptop, adding second display makes nvidia-intel hybrid (or opengl) in browser becoming slow

I love to play starblast.io (a small 3D game in browser).
Since I’ve Manjaro, I cannot solve this problem.
I start my laptop without dual screen (HDMI not connected). I can play the game (some latence but maybe, performances are lower than windows 10 ?).
Then, I connect my dual screen (LG Ultrawide) and immediately, performances falls.
My PC is modern : DELL G7 7700 with i7 and 16GB RAM and RTX2060 graphic card.

Some troubleshooting commands:

prime-run glxgears                                                                                                                                      ✔ 
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
715 frames in 5.0 seconds = 142.955 FPS
714 frames in 5.0 seconds = 142.744 FPS
715 frames in 5.0 seconds = 142.967 FPS

Some others commands (but I don’t know what they’re for):

I feel this last settings is used by browsers for rendering. That’s why starblast.io is using 100% CPU.
