@bfun I've been having that exact issue with Chrome for awhile. Hopefully they fix it with an update.
Not had this problem with Chrome and I leave it open for days, if not weeks at a time and just lock my system. Chrome 90 and Windows 10 20H2.
I run my laptop right next to my desktop. Same version of Chrome on both. Only the desktop seems to have the issue. I think it started a couple of months back.
Try this. Fixed the Chrome freezing issue for me: 1. Go to your address bar are type in chrome://flags 2. In the search box, type 'occlusion' 3. When 'Calculate window occlusion on Windows' pops up, change it from 'Default' to 'Disabled' https://www.windows10forums.com/threads/chrome-freezes-after-sleep-or-after-inactivity.7081/
Chrome now hides this setting. New way to fix this: - Right click the Chrome shortcut. Click Properties. - In the Target address, it will show an address in quotation marks. After the right quotation mark, type --disable-backgrounding-occluded-windows (with the space at the front... and make sure you're using a double dash) - Click Apply, then Ok
