Hello, I am new to this forum.
I wanted to try out CS:GO on Linux and I chose Ubuntu Mate as my OS.
I installed the latest amd drivers and followed the instructions to do so. When the installation was over I restarted my PC and then these bars appeared on both sides:
I used my phone's camera because they don't show up on the screenshot that I took.
When I uninstalled it, they disappeared and after the reinstall they appeared again.
Can you help? Thank you!
