I switched to a new nvidia gpu and new larger monitor... The exact same problems.
I still dont know if this is a general problem or just is part of my configuration. I installed latest short lived branch driver from nvidia (NVIDIA-Linux-x86_64-358.16.run) and it worked right away. I will stick with this for now I would like to be of more help with this issue, but I dont know what else to try. Im willing to do more tests upon request :) Please, feel free to close this bug if you think this is only happening in my machine > cheers!
