Code/syntax highlighting doesn't work

[bravoalpha79]

Describe the bug

Similar to closed issue #2444:
When the workspace is loaded, the code is displayed as plain white text, with no syntax highlights.

Restarting the workspace and logging out/in of Gitpod didn't help.

Steps to reproduce

Affected workspace: https://e2eb8b73-0e99-4f1b-9108-81386ff2ae9a.ws-eu03.gitpod.io/#/workspace/curl-command-line

Expected behavior

Code highlight works.

This workspace is also affected
also reported in #2713
workspace:
bd9c91cd-2953-41f2-b11f-247eba7186df
PaoloAlbanese/cocktails - master

all the code is just black and white
shortcuts like ctrl+/ don't comment outs selection
the ports are not available, they just read:
8080– detecting...
3306– detecting...
33060– detecting...

Mine on #2713 works now

Hi ! I've managed to fix this problem by turning off Kaspersky Security Cloud.

I have encountered the same issue: https://c3bb1940-aa22-4467-b066-32c73fcccbf7.ws-eu03.gitpod.io/#/workspace/devxconf.org

[nisarhassan12]

I just tried stopping and restarting the workspace and it fixed the problem for me.

I often have this issue with pretty much any workspace. Sometimes it works, sometimes it does not. There's no consistency as to why. Often, all gitpod theme icons do not load either.

• I have removed extensions
• I minimised my dockerfile commands
• I changed all settings to default.

Still the issue persisted.

However, I turned off Adblock Plus and Ghostery on Chrome, extensions for blocking ads and trackers, and the rate of the issue occurring has gone down quite a lot.
I don't know why they seem to have an impact but they do. Previously I culd only load up a workspace successfully 1/5 attempts, now its the opposite. I fail 1/5 attempts. I recommend people disable their blockers to see if there's any impact.

[akosyakov]

There are timeouts on downloading extensions (quite high though like 5s per an extension). Maybe blockers (or some other software manipulating traffic on your machine) lead to hitting such timeouts.

I have one computer running windows and one computer running linux sharing the same internet connection.
On my linux machine syntax highlighting works fine in all browsers.
On my windows machine syntax highlighting does not work at all.

Hi, I have the same problem here on all workspaces that I launched for the last 5 days.
Example workspace: https://olive-cattle-s3uc7gc3.ws-eu03.gitpod.io/

In addition to above.

It does work on Android smartphone with Chrome for Android.

It didn't work on windows 10 computer with Firefow or Chrome or Edge. Same
First I disabled all browser extension and updated browsers to latest version. > No change
Then I disabled Kasperky Antivirus > it worked.

Lastly when it it works I still get the above error message: "Access to XMLHttpRequest at 'https://open-vsx.org/vscode/gallery/extensionquery' from origin 'https://olive-cattle-s3uc7gc3.ws-eu03.gitpod.io' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

Then I disabled Kasperky Antivirus > it worked.

Could it prohibit some network traffic like wasm files?

Lastly when it it works I still get the above error message: "Access to XMLHttpRequest at 'https://open-vsx.org/vscode/gallery/extensionquery' from origin 'https://olive-cattle-s3uc7gc3.ws-eu03.gitpod.io' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource."

It is unrelated. It is misconfigured Open VSX registry, but we work it around but doing the request on the backend.

@akosyakov
The relevant message in Chrome console may be this one:
Access to fetch at 'https://blobserve.ws-eu03.gitpod.io/eu.gcr.io/gitpod-dev/ide/code:hotfix-2021-04-15.2/__files__/node_modules/vscode-oniguruma/release/onig.wasm' (redirected from 'https://brown-jay-4144tgze.ws-eu03.gitpod.io/node_modules/vscode-oniguruma/release/onig.wasm') from origin 'https://brown-jay-4144tgze.ws-eu03.gitpod.io' has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

I also got this error specific to Kaspersky:

Refused to connect to 'wss://gc.kis.v2.scr.kaspersky-labs.com/[...]%2Fwebview-black-firefly-i66xqqyn.ws-eu03.gitpod.io%2Fout%2Fvs%2Fworkbench%2Fcontrib%2Fwebview%2Fbrowser%2Fpre%2Ffake.html%3Fid%3D7467c924-0f71-4e53-9567-d71b2928ef03&nocache=1618858835990' because it violates the following Content Security Policy directive: "default-src 'unsafe-inline' 'unsafe-eval' data: https: http: blob: https://webview-black-firefly-i66xqqyn.ws-eu03.gitpod.io". Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

To use Kaspersky with Gitpod, my current workaround: In Kaspersky 2020 > Settings > Networks settings > Traffic processing > Disable : "Inject script into web traffic to interact with web pages."

I was able to reproduce this issue today with Edge running on Windows 11. Chrome works fine.

Hey @code2k13, it's probably due to some extension or browser config of yours on Edge. You might find something interesting on your console logs.

Disable or uninstall the "Color Identifiers" extension and reload the workspace. It worked for me.
