Every time my laptop resumes from standby the Chromium browser becomes frozen. Graphically, it means that it leaves an unresponsive black square on the desktop. Sometimes, but not always it would start working only after shutting it down and restarting. Mostly, it would still start without a window.
Google Chrome does not freeze that way which makes me speculate that it has to do something with the new Pepper Flash player. I was searching the web and found reports about freezes upon resuming from standby in other programs. The reports blamed the new linux kernel > 3.10.. I booted with kernel 3.2. and Chromium indeed did not freeze.
Any workarounds while waiting for the fix of the kernel?
sudo apt-get install pepperflashplugin-nonfree), but I should note that it's unlikely that that's the issue.
