Started seeing these strange gradient lines across the screen in Google Chrome, but they often don't go beyond the fold of a website. The mouse is above the lines and they don't take up the whole screen, making me think it is a software issue. I am using an external display, but the result is the same on my almost 4 month old 16" MacBook. Safari is not showing the lines.... Any ideas?
MacBook Pro 16", macOS 10.15
That looks like some browser rendering issue with the GPU hardware acceleration. Whether it is due to a hardware issue, driver issue, or browser issue is hard to say. Browser GPU acceleration does still has some kinks to work out.

I turned off Hardware Acceleration in Chrome and that fixed it for Chrome, but still happening for Teams.

Try turning off GPU Acceleration in the Teams' Settings. Click on your icon badge in the upper right corner of the Teams app and select "Settings". On the "General" tab make sure to check the box for "Disable GPU hardware acceleration (requires restarting Teams". Make sure to quit Teams after making this change. When you relaunch Teams the GPU acceleration should be disabled.
@HWTech I understand disabling hardware acceleration in programs "fixes" the issue. However are we not really masking the issue? If programs from different developers are displaying the same symptoms, does this not very clearly make it an Apple problem? Especially since it's occuring exclusively on the 16" pro models?

have also seen this same thing on my macbookpro 16" (also using external screens) - seems to mainly affect Chrome (usually the devtools inspect window but also other normal site windows) i have also seen it on the whatsapp desktop app. Does seem that disabling 'Use hardware acceleration when available' in Chrome does make it go away. Any information on if this is hardware or software?

If it only occurs on matlab, then they may be using GPU hardware acceleration as well. Check the matlab preferences. If this is the only app which gives you problems, then it is a software issue which will need to be resolved by matlab developers.
and with hardware acceleration turned off

The 16" model is known to have some GPU issues. Try turning off GPU Hardware Acceleration within the Chrome settings.
Thank you! Turned off in Chrome settings and no problems since.

FWIW, I've also got the 16 inch MBP (Oct release), latest MacOS, latest chrome, and don't have the problem with or without acceleration; also tried it out on a 2015 MBP with no problem
That helped, Teams is back in business.
Thanks
You're welcome. Thanks for the feedback that it worked.
