d3d11: failed to create buffer

[OpticalOverride]

One of my players is getting a very strange error… Apparently their game will freeze (just the image) but the audio will continue on. According to another thread ( Crash on Master build ), the “[0x887A0005]” error means the graphics card drivers crashed. Not sure exactly what that means or how I should fix this… They have plenty of VRAM for the game (on low settings it uses about 80 MB). Here is the output log.

I don’t know the answer specifically, though that driver is over 2 years old.

[Ultroman]

I get the same problem with “Development build” and “Script debugging” turned on. And my drivers are up-to-date.

[dtupper]

Getting the same issue, in the editor, with up to date drivers. Unity support linked me this issue: Unity Issue Tracker - Editor/Player freeze and Crash with error message "d3d11: failed to create buffer" after moving canvas

I have done everything short of a full format and reinstall: GPU drivers update, full uninstall/reinstall of Unity (including clearing registry), new projects, everything. The only thing that works is swapping to D3D9-- which, of course, breaks all my shaders. Using the -force-driver-type-warp launch option also appears to fix it, but slows Unity down to a crawl.

I cannot upgrade beyond Unity 5.6.3p1 due to project constraints (VRChat)

E: Forcing OpenGL 4.5 via launch options is a viable workaround.

[ryo0ka]

Thank you dtupper for the workaround suggestion. Forcing OpenGL 4.5 did solve the issue.
For anyone in the issue (on Windows): Specify -force-glcore45 as a launch option of your Unity client.

[dheera1996]

this still exists in 2018.2 ? d3d9 is deprecated in 2018.2… any update on the issue?

[Drowning-Monkeys]

bump

[xushunwangdh]

This issue still happed in 2018.4.3!

Anyone knows how to fix it ?

[mQe]

Seriously no fix for this?
It’s making development practically impossible

[petrvostrel]

Can confirm this issue is there again in 2018.4.11. Does it mean newer versions suffer with this too?

[system]

I receive this when running Unity in batch mode for building my game with Unity 2018.4.15f1

Unity 2019.3.9f1 Everything works fine in the editor, but the win build freezed at some point with that errors as the last entries in the Player.log and i have no idea how to fix that…

[DaikiHirayama]

I’m getting it now as well.

[Amitloaf]

2019.3.7f confirmed to happen too

[the_mr_matt]

I’m getting the same errors in 2019.3.0f6. Output log: Dropbox - File Deleted - Simplify your life

Unity editor freezes but audio continues. This only happens when I’m loading a specific scene, and does not happen on all occasions.

This happens about every half hour or so. Makes development near impossible.

Send a bug report with the scene, it might help the unity team to reproduce and fix it

[Mike_Weicker]

2019.4.8f1 LTS
After a couple years of development, a select few of our users get this error seemingly randomly. The logs are spammed with some combination of these 3 types of errors.

d3d11: attempt to lock null buffer
d3d11: failed to create staging 2D texture w=128 h=2 d3dfmt=10 [887a0005]
d3d11: failed to create buffer (target 0x1 mode 1 size 6720) [0x887A0005]

We see anywhere from 500 to 10,000 lines of errors before a crash happens. I suspect that it is just running out of memory when this happens.

[Frieza]

I’ve had a player report a crash in a live build of my game with dx11 using Unity 2019.3.13f1, unfortunately I cannot force them to use GL, I would be interested to know what is causing this and if there’s a work-around I could use?

[Radu1397]

Having same type of errors running a game called genshin impact, never had issues with d3d11 before…

[Coredumping]

Had a similar issue in Unity 2017.4 caused by Calling Graphics.CopyTexture to a Texture2D created in code with mipmapping enabled, and having less than full resolution for texture quality, e.g. QualitySettings.masterTextureLimit > 0. Unity seems to crash or freeze in this case using DirectX 11.
