I copied Copay-linux.zip from Releases page

https://github.com/bitpay/copay/releases

I run ./Copay command and saw errors in console

[12044:12044:0612/165916.674228:ERROR:sandbox_linux.cc(345)] InitializeSandbox() called with multiple threads in process gpu-process.

There is written

After upgrading to CEF v58 (Chrome/58.0.3029.81) this error message stopped appearing.

Maybe upgrading your dependencies connected with chrome drivers can help to solve it.
