Issue descriptionUserAgent: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/54.0.2840.87 Safari/537.36 Steps to reproduce the problem: 1. Open many windows with many tabs 2. Open a Steam forum in one tab: e.g. http://steamcommunity.com/app/444930/discussions/2/ 3. Go work in other chrome windows for a while, maybe go idle for a while 4. Go back to Steam forum window 5. Hover mouse over forum threads - observe that popup is slow to respond 6. Move window 7. Hover mouse over forum threads again - should be smooth now What is the expected behavior? What went wrong? Browser should not be throttling foreground windows. Did this work before? Yes Don't know. It seemed fine on my previous PC. Only noticed problem on new PC (i7-6700K, GTX 1080 latest drivers) Chrome version: 54.0.2840.87 Channel: stable OS Version: 6.1 (Windows 7, Windows Server 2008 R2) Flash Version: Shockwave Flash 23.0 r0 This affects everything - including video playback sites such as Netflix and Youtube. It also affects tab bar animation (e.g. when closing a tab, the animation is very laggy, not smooth, low fps).

At the moment, I wasn't able to reproduce it, but it's not consistent and I do believe I've seen it as recently as in the past few days. I'm also not entirely sure that the issue is limited to Chrome. I suspect it might somehow be an issue with Windows or graphics drivers as I feel I've seen very similar behavior on occasion in other applications, but Chrome is where I tend to notice it. I'll comment again if I see it again.

I haven't seen this recur specifically in Chrome lately. Although I seem to have similar issues occur in basically all applications that do rendering. I suspect this has to do with either Windows or graphics drivers. However, I've had no (useful) response from anybody about it at the nvidia forums yet. Also might be worth noting that I have a 144hz monitor running at 120hz.

... and it just happened again. Another way I can detect this is by sliding a tab left and right along the tab bar. If the issue is occurring, the animation is not smooth. Moving the entire window makes the animation smooth again. But, like I said, I'm not convinced this is actually Chrome's fault.
