Refer to this issue for more info: #719Įdit: I've managed to get a debian VM running and performance does indeed tend to be much poorer. Without this, a chrome restart will cause all suspended tabs to show the default blockhead extension favicon. To fix this, I've had to add extra checking on chrome startup and post tab suspension to ensure that the correct favicon is displayed. It is due to some changes in newer versions of chrome which causes issues with the display of favicons of suspended tabs with the older version of the extension. Just for some background into why these newer versions are less performant than the older release. And if you could take another log for me that might be useful. There has been one small performance improvements (bugfix) which may help since we last tried. Although my testing on Ubuntu is non-existent.

You're right that your laptop should not suffer from performance issues. There was a bad logging message in the code which erroneously referred to screen captures.
