Vscode: Minimap and integrated terminal rendered incorrectly on Arch Linux

[deweiwork]

• VSCode Version: 1.34.0
• OS Version: 5.1.5-arch1-2-ARCH ArchLinux

Steps to Reproduce:

Bug as shown in the picture above.

I think this is a problem with Electron,

because my other application has same problem too (haroopad),

this application is also based on electron.

My electron version is 4.1.4 .

Does this issue occur when all extensions are disabled?: Yes/No
yes

@JAicewizard Yes, thanks!

Most of these issues I've been closing but I'll keep this one open for a bit so it's more discoverable.

The problem is related to your graphics drivers and/or Chromium not correctly blacklisting your configuration. Your current options are:

• Update mesa (people have indicated below that this fixes the issue)
• Update your graphics drivers 🤞
• Launch vscode using code --disable-gpu (you can add this to your code.desktop file but it will change back after an update)
• Disable canvas usage in terminal and minimap with these settings:
  "terminal.integrated.rendererType": "dom", "editor.minimap.enabled": false

This sort of issue should hopefully resolve itself when we update Electrn (https://github.com/microsoft/vscode/issues/61787). You can vote on https://github.com/microsoft/vscode/issues/15211 to make it more convenient to disable GPU usage.

Use code.desktop file to start vscode without gpu:

This is useful for me.

Not actually relevant, but just adding - In my original report, I said I hadn't observed display output problems in any other application. Well, now I have. On Steam, which also uses Chromium (probably CEF). The Friends&Chat window won't open, and the Steam News window shows up blank.

(edit) image removed; the Steam bug is actually not related (although there is one - Bug 110721 - graphics corruption on steam client with mesa 19.1.0 rc3 on polaris - that's not the one I was observing). Its description and proposed fixes can be found at the following locations:

I have literally had that issue for like 2 years, its nothing new for me.
I have seen steam displaying the news/store as a bug at this point :P

I updated mesa to 19.0.6-1 and it fixed it for me(at least, for now)

@JAicewizard @Tyriar
Hi:
Today, I update vscode and mesa to newest version with ArchLinux.
Minamap and integrated terminal are working normally now!

[ranolfi]

Confirmed fixed on Mesa 19.0.6. See Bug 110761 - Huge problems between Mesa and Electron engine apps.

Thanks @ranolfi, closing off since it seems the root cause was found.
