説明
Text rendering is abnormally thin when allowTransparency=true with the webgl renderer even when the background color is completely opaque.
allowTransparency=false: 
allowTransparency=true: 
I think this is also mentioned in this comment in another bug.
Details
- Browser and browser version: Chrome 106.0.5249.119
- OS version: Linux (Debian)
- xterm.js version: ToT @ 376f0d99721b6ec056b15551f46237b80e24b55b
Steps to reproduce
- Run the demo page
- Set theme to
lightand font family to"Noto Sans Mono" - Execute
echo -e '\033[33mhello world\033[m' - Observe that the rendering is OK
- Check the "allowTransparency" toggle
- Reload the webgl addon because the rendering is messed up: Uncheck and then check the webgl checkbox under "Addon". (I believe reloading the addon is NOT what is causing problem here)
- Observe that the "hello world" text is abnormally thin
Note that the light theme have a completely opaque background, so the rendering theoretically should just be the same.
