My take on it: Windows 8.1 has a feature called TDR which may restart the video driver (any not just nvidia as in my case) which makes Thunderbird and Firefox crash. What should happen is that both products recover gracefully from a Windows video driver restart triggered by TDR. Reproducible: Always on Application Build ID 20141107030200 after a video driver restart message in windows eventlog as documented above

Uups sorry it is crash bp-e8da8805-7b6b-4e06-b364-a34a22141111

Searching breakpad for CreateTexture2D turns up more reports that may be related. (Aside: I think I entered a comment and email, seems that did not make it to breakpad, is that a bug in crashreporter)

(In reply to martin from comment #2) > Uups sorry it is crash bp-e8da8805-7b6b-4e06-b364-a34a22141111 This is nvwgf2umx.dll@0x27d3be https://crash-stats.mozilla.com/report/index/e8da8805-7b6b-4e06-b364-a34a22141111 ... Very few of these crashes in the system. (In reply to martin from comment #3) > (Aside: I think I entered a comment and email, seems that did not make it to > breakpad, is that a bug in crashreporter) As best I can tell, your firefox crashes have your address. But your thunderbird ones do not. You'll need to add it. (email addresses are not public, so https://crash-stats.mozilla.com/report/index/e8da8805-7b6b-4e06-b364-a34a22141111 won't show it to you. But I can see them)

If my theory is correct then all those crashes in DirectX are related to Windows TDR. (as written in the referenced bug 1089454 Seaching BP for CreateTexture2D turns up 14 in Thunderbird https://crash-stats.mozilla.com/query/?product=Thunderbird&version=ALL%3AALL&platform=win&range_value=30&range_unit=days&date=11%2F11%2F2014+22%3A00%3A00&query_search=signature&query_type=contains&query=CreateTexture2D&reason=&release_channels=&build_id=&process_type=any&hang_type=any Searching BP for D2D_RECT_F const*, ID2D1Brush* turns up 67 https://crash-stats.mozilla.com/query/?product=Thunderbird&version=ALL%3AALL&platform=win&range_value=30&range_unit=days&date=11%2F11%2F2014+22%3A00%3A00&query_search=signature&query_type=contains&query=D2D_RECT_F+const*%2C+ID2D1Brush*&reason=&release_channels=&build_id=&process_type=any&hang_type=any (I have looked through the local crashreporter directory and found in the log: [11/11/14 06:49:10] Crash report submission failed: Der Vorgang wurde erfolgreich beendet. Which is kind of ambigous, tells me submission failed and then in german "The process was completed sucessfully" Seems that upload was partially sucessful since my data is on BP, but it's missing my comments & email, can I add those after upload? )

Since bug 1154003 is fixed, have you crashed Thunderbird 38/Firefox 38?

trying to reach Martin - no luck so far

reports on crash-stats are rare, and only with Thunderbird nightly. For example bp-4369ae39-bc48-43f9-8846-ff5392150910. If this is fixed by bug 1162520 as ashughes suggests then this should be gone in version 38. Martin unfortuantely has not responded to confirm. Marking WFM until we hear otherwise
