User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:56.0) Gecko/20100101 Firefox/56.0
Steps to reproduce:
Basically every part of the UI is not visually updating when it's supposed to.
About box:
- Open the About box.
Urlbar:
- Enter any text in the Urlbar.
- Navigate up and down with arrows.
Videos:
- View any YouTube video.
This is similar to bug 1712265 and probably related, but that bug was closed prematurely and I'm still seeing this in Firefox 90b6. The issue first appeared when Firefox Developer Edition updated from 89b15 to 90b2.
This bug does not occur in safe mode. However, it happens reliably outside of safe mode even after reverting to a vanilla profile. If this is the same issue as bug 1712265, then whatever fixed that bug for Firefox 91a1 should be investigated and added to the Firefox 90 beta cycle before 90 is released.
I tried turning on Webrender and restarting Firefox Developer Edition; it did not change the outcome.
Actual results:
About box: Nothing renders; the about dialog has a ghost copy of whatever was on screen beneath it.
Urlbar: Navigation appears to be frozen; it isn't, but it isn't visually updating. (Hitting Enter will navigate to the correct item, but you can't see which item is selected because nothing has visually refreshed.) The bar and navigation don't re-render unless you mouse over another UI button. At that point part of the screen may refresh, but nothing fully refreshes until a tooltip appears.
YouTube videos: Audio plays normally, but video frames don't update unless you move the mouse over other elements on the page.
What all of these cases have in common is that the renderer chokes and does not visually update unless some outside factor forces it to. In some cases you can make part of the screen refresh.
Expected results:
In all cases, the UI should refresh and display as it normally would.
About dialog: The "About Firefox" dialog should be rendered.
Urlbar: Moving up and down should scroll through history/suggestions and the navigation should cause the UI to visibly change, so you see what you've selected.
Videos: Frames should advance as they normally would instead of staying frozen on one frame.
