`text_background_opacity` doesn't work on win11

[meijieru]

What Operating System(s) are you seeing this problem on?

Windows

WezTerm version

wezterm 20210814-124438-54e29167

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

No, and I'll explain why below

Describe the bug

With the following config, it doesn't have any effect when I change the text_background_opacity

text_background_opacity=0.1 text_background_opacity=1.0

To Reproduce

1. Use the config below.
2. Varies text_background_opacity

Configuration

window_background_image = "D:\\document\\nextcloud\\picture\\comic\\EVA_OneHalfLight.jpg",
  window_background_image_hsb = {
    brightness = 1.0,
    hue = 1.0,
    saturation = 1.0,
  },

  window_background_opacity = 1.0,
  text_background_opacity = 0.1,

Expected Behavior

The background image should be more transparent when text_background_opacity goes down.

text_background_opacity only affects cells whose background color is changed to something other than the default background color, so if text had its background color set to red, and you had set text_background_opacity = 0.5 then you'd see more of a pink color when using a white background image.

window_background_opacity controls the opacity for cells that have the default background color.

It doesn't work either.

If I understand correctly, it should affect the background of Windows.old/ here.

text_background_opacity = 0.1

text_background_opacity = 1.0

In addition, how can I blend the background image and the background from colorscheme? I want the image to be opacity over the colorscheme background instead of the desktop for the visibility of texts.

Also, window_background_opacity doesn't work if window_background_image is not set. In addition, change window_background_opacity=0.1 deteriorate the font rendering.

window_background_opacity=0.1

window_background_opacity=1.0

Update: window_background_opacity in range [0.95, 1.0] works, other doesn't.

Please try the nightly build; there have been some fixes around opacity handling

Looking forward to it. How can I do it using scoop?

[wez]

I don't know if scoop knows how to get the nightly builds, but there are a number of other options here: https://wezfurlong.org/wezterm/install/windows.html

[meijieru]

In the nightly build, small window_background_opacity & text_background_opacity works. Though the fonts are still deteriorates.

window_background_opacity=0.15

Could you try again with the latest nightly?

[meijieru]

Download the latest build from https://github.com/wez/wezterm/releases/download/nightly/WezTerm-windows-nightly.zip, still have the problem.

[wez]

OK, I think this is now actually fixed in the very latest nightly; please try it and let me know!

[meijieru]

Confirm that the problem is solved.
