Vscode: Laggy Terminal

Extremely laggy terminal after the last update. Not sure if this is because of some extension?

It's because of the Chromium upgrade, workaround is to launch with code --ignore-gpu-blacklist

[Tyriar]

Actually there was a bad regression recently separately to the Electron change. I'll use this issue to track this one. https://github.com/xtermjs/xterm.js/issues/1620

[algorusa]

not only terminal but startup as well

Any word on this? I'm on 1.27.2 (windows 10) and seeing a 1000 line or so terraform operation in git-bash lock up across two separate Code instances, plus getting the dialog saying window is not responding in both instances. Very really not good.

[Tyriar]

@fractos you're probably seeing issues with electron's canvas acceleration, see https://github.com/Microsoft/vscode/issues/56517

[Tyriar]

I'm locking this as this specific issue is fixed, see https://github.com/Microsoft/vscode/issues/56517 for GPU rendering slowness.
