Ubuntu MATE: Fixing ALT + TAB being really slow

On my Ubuntu MATE machine, switching applications with ALT + TAB was impossible, because it took nearly 2 seconds. The culprit appears to be an "UX improvement" gone bad: MATE renders a live screenshot of each running application inside the application switcher.

Fixing this is simple:

  • Open "Window Preferences"
  • Either uncheck "Enable software compositing window manager" or check "Disable thumbnails in Alt-Tab"

Once an application no longer requires constant development, it needs periodic maintenance for stable and secure operation. makandra offers monthly maintenance contracts that let you focus on your business while we make sure the lights stay on.
