Hmm, I could not reproduce the problem with my Win10 PCs.
Asif Youssuff, can you reproduce the problem with other Win10 PC?

Comment 3

[Asif Youssuff]

Sotaro, I don't use any other Windows PC with enough regularity to try to reproduce the issue.

Comment 4

[Sotaro Ikeda [:sotaro]]

:gw, do you have any ideas about a cause of the problem?

Comment 5

[Glenn Watson [:gw]]

I also can't repro locally on my Win10/Intel machine. Does it still occur if DirectComposition is disabled in about:config?

Comment 6

[Asif Youssuff]

What is the preference for DirectComposition in about:config?

Setting gfx.webrender.compositor to be false and restarting should do it, I think.

@Asif: Could you also try updating the intel graphics driver?

Comment 9

[Asif Youssuff]

I haven't seen the issue in the days since disabling DirectComposition.

I'm pretty sure I was running the latest version of the driver provided by Windows Update - I have now downloaded a newer version via Intel's website.

I went ahead and re-enabled DirectComposition since updating the driver this morning.

Asif, did the new driver version solve the problem with DirectComposition enabled? Thanks!

Comment 11

[Asif Youssuff]

Andrew, I honestly stopped running Windows on that machine due to the awful performance on it - and it didn't happen all the time, so I'd probably have to run it for a somewhat extended period of time. I'll go ahead and do that now since I have another needinfo for that same hardware.

It looks like the new driver version fixed the issue.

Comment 13

[Asif Youssuff]

Kris, isn't this still a bug with the driver version I initially reported the bug with?

Comment 14

[Kris Taeleman (:ktaeleman)]

@andrew: Asif has a point, should we block the driver version?
