I'll try to reproduce this when I get back to Toronto

I wasn't able to reproduce this on a AMD Radeon HD 5670 with the 19.12.0.0 driver. Paul the crash is at atiumdva.dll@0x14137 can you give us an idea of what the driver thinks is going wrong here?

The issue apparently occurs on a Hybrid Graphics/PowerXpress system and the crash occurs in the Video Acceleration driver, the location is roughly in the DecodeFrame() function though I can't fully match up the offset right now. Need to set up a repro here on a debugger.

Does this repro on any more recent hardware?

AMD Bug is filed and investigated

the signatures in this bug might be related to the enabling of d3d11 dxva as well (the signatures are just the most popular ones - there will be a number of other ones for amd gpus still).

(In reply to philipp from comment #7) > the signatures in this bug might be related to the enabling of d3d11 dxva as > well (the signatures are just the most popular ones - there will be a number > of other ones for amd gpus still). I'm working on bug 1273691 first, which will make it easier to blacklist more DLLs as needed. Keeping reminder to self, to add these suggested DLLs later on.

Comment on attachment 8754620 [details] MozReview Request: Bug 1255732 - Disable D3D11 for some atidxx32/64 DLLs - r?cpearce Approval Request Comment [Feature/regressing bug #]: D3D11 crashes in 47+ [User impact if declined]: many crashes per week in beta 47. [Describe test coverage new/current, TreeHerder]: No new try as it's just a pref change adding more DLLs. [Risks and why]: Only a pref change that adds some DLLs; Tiny risk in disabling too many DLLs, but we're falling back to proven D3D9, so it's not so bad. [String/UUID change made/needed]: None. Requires uplift of bug 1257028, bug 1273691, bug 1274115, bug 1274127, bug 1274132, bug 1273504 first.

i bought a rx 480 recently and since i installed it on my pc firefox crashes every hour. here three example links to the last crashes: https://crash-stats.mozilla.com/report/index/09e74f17-b67c-41af-a017-27ad42160831 https://crash-stats.mozilla.com/report/index/c6a3a601-4630-4c87-af16-a8aae2160831 https://crash-stats.mozilla.com/report/index/655b2856-a8c3-4a54-b24a-f4d5e2160831 all mention this bug so i thought you maybe can reopen it to fix my problem as well. im using the most recent amd driver 16.8.2 on windows 10. (i dont have any issues on ubuntu 16.04)

it certainly happens on youtube. but i think at least one or two of the last 15 crashes were not connected so i guess i will do what you recommend.

If you have clear steps to reproduce the crash, please detail them when you open the new bug. Also, attach to your bug report the data from about:support (in particular the Graphics section).

okay did that here is the bug for your reference as well: https://bugzilla.mozilla.org/show_bug.cgi?id=1299520
