Electron enables hardware accelerated graphics by default, but some graphics cards have issues with hardware acceleration which means the application will launch successfully but it will be a black screen.
**Workaround:** if you set the `GITHUB_DESKTOP_DISABLE_HARDWARE_ACCELERATION` environment variable to any value and launch Desktop again it will disable hardware acceleration on launch, so the application is usable.

### Failed to open CA file after an update - #4832
A recent upgrade to Git for Windows changed how it uses `http.sslCAInfo`.
An example of this error:
> fatal: unable to access 'https://github.com/\<owner>/\<repo>.git/': schannel: failed to open CA file 'C:/Users/\<account>/AppData/Local/GitHubDesktop/app-1.2.2/resources/app/git/mingw64/bin/curl-ca-bundle.crt': No such file or directory
This is occuring because some users have an existing Git for Windows installation that created a special config at `C:\ProgramData\Git\config`, and this config may contain a `http.sslCAInfo` entry, which is inherited by Desktop.
There's two problems with this:
- Desktop doesn't need custom certificates for it's Git operations - SChannel uses the Windows Certificate Store to verify server certificates
- this config value may point to a location that doesn't exist in Desktop's Git installation
**Workaround:**
1. Verify that you have the problem configuration by checking the output of this command:
```
> git config -l --show-origin
```
You should have an entry that looks like this:
```
file:"C:\ProgramData/Git/config" http.sslcainfo=[some value here]
```
2. Open `C:\ProgramData\Git\config` and remove the corresponding lines that look like this:
```
[http]
sslCAInfo = [some value here]
```
