1449336 - Rendering errors when disconnecting external display

Status: RESOLVED WORKSFORME

(Core :: Graphics: WebRender, defect, P2)

Description

[Matthew Gaudet (he/him) [:mgaudet]]

Attachment: Rendering errors

STR: 

1. Connect Retina external display. 

2. Launch nightly with gfx.webrender.all:true enabled (I used mozregression --launch 2018-03-27 --pref gfx.webrender.all:true)

3. Disconnect external display. Wait a few seconds, and then see the rendering for the window will go bad.

4. Restoring the cable to the external monitor and rendering returns to expected.  

I suspect this is related to the graphics switching: When you plug in the cable, before the attached monitor even turns on, the rendering returns to normal (mostly). I'm seeing a couple odd rendering glitches like a flashing bar where the horizontal scrollbar should be on this text box right now (though, I can't get a screenshot that conveys the issue, and don't have a screen recorder installed at the moment)

The above about:support log was grabbed while the rendering was errored (in case it matters)

Comment 2

[Maire Reavy [:mreavy]]

Hi Matthew, is this bug still happening?  Can you repro?  Thanks!

Comment 3

[Matthew Gaudet (he/him) [:mgaudet]]

AFAICT, this now seems to be working (even on the originally reported build, so the fix may have been an OS update). 

Closing as WORKSFORME.
