Nothing to do with the internet. I get freezes offline as well. I suspect Nvidia Drivers as more and more of us seem to be getting these lately. I get them on Windows10 and Linux. For me, turning down Anisotropic Filtering helps a lot.
Thanks Axel. My graphic card is nvidia Ge force 1050. I don't find "anisotroping", for changing.
I drive on gpl from 2013 to 2017. I stop gpl in 2017.
I used windows 7 during this period, with an old graphic card. Never freeze during this period.
Now, I have changing my computer in 2018, and I am return on gpl this year. I have repetitive freezes...
