I've had a recurring issue since last week where I wake from sleep on a new external monitor, and several of my already-open Chrome tabs have their content resized (i.e. into a 600x600 viewing area).
This doesn't affect all tabs, but the websites that are affect are not consistent. For instance, Gmail wasn't affected today, yet it was last week when this happened.
Current version of Chrome: 38.0.2125.111; OS X version: 10.9.5. In Mission Control, "Displays have separate Spaces" is enabled.
Things I've tried to correct the problem:
- dragging window to different display/monitor -- this fixes the issue if the problematic tab is in focus. As soon as Chrome window is on the other display, it apparently triggers a re-rendering of the page.
- resizing Chrome window -- this just causes the viewing area to scale with my resizing
- hard refresh (Cmd+Shift+R) -- viewing area stays the same
- opening website in new tab -- new tab viewing area is fine, but old tab remains the same
