Red Eclipse

Hi!
I've recently installed 1.5.1. From the Ubuntu Store, and then I installed 1.5.5. because of the new features!
In version 1.5.1. I had no problems, but in 1.5.5, when I join a game the screen started flickering, flashing, I think it is some kind of render or OpenGL issue, but I can't fix it!
OS: Ubuntu 16.04 LTS
Memory what is detected by Ubuntu: 3,8 Gig
GPU Detected by Ubuntu: Intel® Sandybridge Mobile
Actual GPU: Nvidia Geforce GT 525M & Intel graphics 3000
Processor: Intel® Core™ i7-2630QM CPU @ 2.00GHz × 8
OS type: 64-bit
Keep in mind, this is a laptop!

What does the console output say when you boot up the game?

On first impression it seems your NVIDIA OPTIMUS switching setup isn't being triggered. You will probably need the official NVIDIA drivers to achieve this properly, rather than using the ones bundled with your package manager.
