I'm using Google Chrome, Version 39 (64-bit), under Kubuntu 14.04.1 LTS (trusty).
Often, the browser's window becomes invisible after returning from standby, or after opening the window after it was minimized (either by clicking on it in the panel or selecting it among open windows with Alt+Tab).
The only thing that helps to make Chrome visible again is to switch to a TTY by Ctrl+Alt+F1-6 and then back to GUI with Ctrl+Alt+F7.
This has been quite annoying. I would greatly appreciate any solutions/workarounds?
UPDATE: I notice that it happens almost every time after standby/lockscreen when Chrome's window has been in the foreground before.

The issue seems to be connected to the compositer feature of KDE4 (or with Desktop Effects). If the Chrome window becomes invisible click Alt + Shift + F12 to switch on compositing and it will become visible instantaneously. I could no longer reproduce this behaviour with compositing on.
1I want to tell you to use Firefox as a solution (bad joke) :)
Otherwise
Try this
Open terminal,
sudo apt-get remove --purge google-chrome-stableafter that, re-install one of this version
sudo apt-get install google-chrome-stableor
sudo apt-get install google-chrome-betaor
sudo apt-get install google-chrome-unstableif you want to install via or wget
32bit
wget
sudo dpkg -i google-chrome-stable_current_i386.deb
sudo apt-get -f install64bit
wget
sudo dpkg -i google-chrome-stable_current_amd64.deb
sudo apt-get -f installYou have many options now probably one of that can solve your problem
