I just upgraded to 4107 and have vertical orange bars in many locations where there should be some sort of icon or image. I am on WSL2 Ubuntu and I have never seen this problem before the upgrade. I have A File Icon and those seem to be working ok, but the folder icon is vertical bars as well as the close tab image.
Vertical Orange Bars
It looks like you have a theme override. See if this fixes it https://github.com/sublimehq/sublime_text/issues/4230#issuecomment-847973408
My directory structure looks nothing like that mentioned. My package folder is under a sublime text 3 folder which is what I thought I installed.
For example:
/home/<my_name>/.config/sublime-text-3/Packages
But the upgrade has me on sublime 4. Running tree on User dir shows:
/User/
├── Package Control.sublime-settings
├── Package Control.user-ca-bundle
├── Preferences.sublime-settings
├── Pretty JSON.sublime-settings
└── SublimeLinter.sublime-settings
Running tree on the default theme:
./Theme - Default
└── Default.sublime-theme
If that Theme - Default
folder is in the Packages
folder adjacent to User
, that’s the cause of your problem; In that case it is overriding the same named file from the package that Sublime ships, which is masking changes made for this release.
