Summary: 90-95% of the time absolutely fine. Good speed, responsiveness etc.
See issues listed below, giving details of when things go wrong 5-10% of the time. These issues seem to correspond to when I've opened WhatsApp web. Indeed I'm yet to experience any issues if I don't launch a tab with WhatsApp web in a Chrome session.
See also the errors list of unique errors seen in the terminal (from which I launched Chrome)
| Mac OS X 10.13.2 Beta (17C60c) | |
| Version 64.0.3261.0 (Official Build) canary (64-bit) | |
| Flags used: --disable-native-gpu-memory-buffers --disable-zero-copy --disable-gpu-memory-buffer-video-frames | |
| Running Chrome alongside VMWare Fusion which ensures the discrete graphics card is in use | |
| Tabs open with, variously: | |
| Gmail | |
| Google Calendar | |
| Google Drive | |
| Slack (x 2) | |
| Gitlab pull reviews (lots of diff-based HTML on screen at any one time) | |
| WhatsApp web | |
WhatsApp web seems to trigger something that randomly causes my machine to go into a bad state; but haven't been able to pin that down or reproduce it reliably. The bad state manifests itself as extreme lag in all applications (only resolved by shutting down all applications that are using/rely on the discrete graphics card)
WhatsApp web also causes problem with other tabs. Moving between or closing tabs sometimes (~5% of the time, but common factor appears to be WhatsApp web) leaves "shadow tabs" (is there a proper name for this?), where the contents of the tab I have closed/left are incorrectly rendered in the tab I move to. This then seems to put Chrome into a bad state; only fix is to restart Chrome.
I also experienced an issue where sharing screen in Google Hangouts put my machine into a bad state. Mouse lag everywhere. But in this case, performance instantly restored when I stop sharing screen and close the hangout session (no Chrome restart required). Don't recall having opened WhatsApp web in this session, but I can't be sure.
