Screen Flickering with macOS 10.14.5 & VSCode 1.34.0

See original GitHub issue

Issue Type: Bug

I have my MBP (docked, laptop lid closed) connected to an external 4K display, and the screen flickering is getting pretty obnoxious. Happens routinely when switching tabs. I tried disabling all extensions and running with code --disable-gpu and --ignore-gpu-blacklist which didn’t solve it in my testing. Any ideas on other workarounds?

Ideally I’d want this fixed, and not need to open it from the command line every time.

I had the issue with VSCode 1.52 and MacOS 14.0. Resolved it by setting the option “disable-color-correct-rendering” to false (was true by default).

Open VSCode, cmd+shift+p, Preferences : Configure Runtime Arguments to open the configuration file, then set the property “disable-color-correct-rendering” to false.

This is a problem for me as well. Each tab that I switch causes flickering, if I switch tabs frequently it will get so bad as to cause the monitor to go back, before resetting after a moment. Then the problem will continue.
