MSI gtx1070ti issues in browser

[b1984527]

Hello all, I have an issue with browser webgl rendering. Couple days ago I buy nvidia msi gtx 1070ti videocard, insert it into my PC, and:

1. install drivers
2. choose nvidia drivers in driver manager popup
3. install cuda toolkit by this command: sudo apt-get install nvidia-cuda-toolkit

Then I play little bit in starcraft 2 with max graphics settings, everything gone super smooth, perfect FPS and image, also I notice that temperature is below 55C (coolers start to work only if temperature become more than 60).
After it I play in browser game https://starblast.io/ , and after couple seconds both coolers start to work. Temperature around 60C (with coolers), 30 fps, picture is not clear, there is lags, colors not changed, some text (svg icons most probably) transform into this - https://ibb.co/jp0yCn.

Also, I notice that just surfing internet card have temperature sometimes reach 60C. I can't understand, how surfing internet make card more hot than playing games.

This issue happen in firefox and chromium browsers. Absolutely have no idea what should I do and how to solve this problem.

upd:
today I install windows 10 as second system and everything there work fine. After I install w10, I download latest nvidia drivers from nvidia website, nothing special from MSI. Also I notice that w10 driver version is 391.01 WHQL, and linux 390.25-ubuntu0~gpu16.04.1

upd2:
after I switch CPU drivers from "Do not update CPU microcode" to intel-microcode (open source), browser game start to work with 60 fps, but there is still artifacts instead of some images.

What was the purpose of installing the cuda toolkit? Could this be what is effecting your card?

Absolutely have no idea, I just follow instructions from "how to install nvidia on linux".
