Change window width by dragging left edge of DevTools window. 3. Try to inspect elements. What is the expected result? – Elements highlight without delay. What happens instead of that? – There's a significant delay when moving cursor over different elements. GPU Process usage is high. Please provide any additional information below.

I added a new profile and managed to reproduce the problem – see enclosed screen cast. I'd like to add a couple of thoughts: - I'm NOT able to produce this when using a small/narrow window. The problem seems to become progressively worse as I increase window width. This leads me to think that it may be related to the iMac's high resolution screen. - The problem was not present in earlier versions of Chrome. - I notice GPU Process usage increases also before changing the window-size, so it might not be that relevant.

This problem is absolutely annoying! Responsive development on the iMac is almost impossible
