[Bug] Black screen on 1.22.0

[manilz]

So, when I install ImHex, and open it, or try to open a file with it this is all what I see

[WerWolv]

Hey What version of ImHex did you download? Portable? Portable-NoGPU? Also v1.22.2 does not exist, the latest one is v1.22.0.

From the picture it looks like a GPU issue but I need some more information to really help you

[manilz]

Yes, sorry, i donwloaded stable release (.MSI installer), ran on Windows 10 Home 21H1 x64, i'm using Intel(R) UHD graphics 620, using standard Intel Corporation driver version 27.20.100

Tried to download Portable non-GPU version, this is the result:

Also tried to download portable GPU version, and result is almost the same

Could you send us the logs you get if you launch ImHex from the terminal ?

@cuerv0s I suppose your GPU driver sucks. You could try to use software rendering as a workaround by dropping Mesa3D's the opengl32.dll file next to the ImHex executable: https://fdossena.com/?p=mesa/index.frag

Laptop users don't have modern GPUs and it seems I have similar issue with below hardware in https://github.com/WerWolv/ImHex/issues/886#issuecomment-1383977531. Could MSI installer not check if GPU is available and install NoGPU exe in case GPU is no good?

MSI installed via winget is the wrong exe!

I dropped the mesa3d's opengl32.dll file next to the executable, still black screen, nothing new in the terminal stdout.

[manilz]

Tried the 1.26.2 version portable version (GPU), it's fixed now. Thanks.

[cyberdaddy93]

I am having the same issue. Is there a fix?

[iTrooz]

Hey, please provide your imhex version, plateform, installation type, and logs. Do you have a GPU ?

[cyberdaddy93]

@iTrooz imhex version - 1.28.0 Platform - Windows 11 Installation Type - .msi , GPU - Yes. NVIDIA RTX A2000 8GB Laptop GPU && Intel(R) UHD Graphics

Logs: Log file is empty

[iTrooz]

Could you run imhex from the command line ? Sometimes it shows more logs

Just left hanging and the ImHex application display with a blacked out screen.

Looks like even though you have a NVIDIA graphics card built into your Laptop, Windows decided to use the integrated Intel HD GPU instead. These Intel GPUs and especially their drivers have TONS of bugs and don't work well. Also it probably doesn't have enough VRAM available to load the fonts. Try forcing your OS to use the NVIDIA GPU instead

YES! That worked for me. Thank you for the support, this save it for me. Product looks nice

Had similar problem, but not due to graphic drivers If ImHex boots up for the first time, but then you accidentally close it and cant open again (black screen appears) - you probably messed up your config. So I just removed .config/imhex directory, and it started working again (posting if you have a similar story) (I'm on 1.33.2-1 actually, but thats the first page that pops up, so I'll leave this here)

[paxcut]

In at least one occasion, the only way I could get ImHex to start in a working condition was to remove the entire %APPDATA%\..\Local\imhex folder. Other times removing the file %APPDATA%\..\Local\config\interface.ini is all I needed to remove since this controls the layout. Yet other times restarting Imhex did the trick.
