VSCode lags substantially after disconnecting external monitor

pvande commented 5 months ago

Type: Performance Issue

I normally work with VSCode running across both my laptop's built-in Retina display and an external 4K monitor. When I disconnect my monitor, VSCode becomes extremely sluggish (multiple second delays between an input and a visible result in the worst cases). This sluggishness can usually be remdied by restarting VSCode.

Does this reproduce using https://insiders.vscode.dev with a browser too?

I am also experiencing this issue quite consistency. I couldn't reproduce it with the browser version at https://insiders.vscode.dev/.
