I've made a picture as screenrecord/screenshot can't cath the problem. As you can see the render is still on "General" despite "Extensions" being the current selection. You can see at the top part of the rendering is restarted and is now stuck in the middle.

This makes the laptop almost unusable with its own display. This happens only on the laptop display, not on the external display. The render of portions of the screen does not happen after some events (listed below) resulting in all or part of the screen not being re-rendered. The UX is that nothing happened, but it has. This happens after: * key-stroke while typing sometimes * alt-tab * shift-right to align window to the right * ctrl-pgup/down to switch tab in multi tabs apps. Please note that: * screenshots can't see the problem * also screenrecorder always seem ok, despite rendering being broken.
