New RStudio Version (2022.07.0) Breaks --ds-tab-gradient-dark on MacOS

[grcatlin]

Hi Riley,

Using RStudio 2022.02.0, --ds-tab-gradient-dark works as expected:

However, on the latest build (2022.07.0, and possibly earlier builds) this behavior changes:

I guess they must've swapped something only in the Mac version of RStudio because the Windows version on the latest build works fine - I haven't tried Linux.

Thanks for the cool work!

I mistook it for --ds-tab-gradient-light before, it's actually --ds-tab-gradient-dark and is fixed easily by adding .GND-IWGDKS to the following section in the css file:

/* Source editor tab overflow gradient */
.rstudio-themes-flat
  .rstudio-themes-dark-grey
  :-webkit-any(.GGBOEFPDDS, .GD15MCFCCS, .GCHYANPCES, .GEL-OVUBOR, .GND-IWGDKS) {
  background: var(--ds-tab-gradient-dark) !important;
}

@grcatlin I'll get this fixed, thanks for the help. Most of RStudio's css is generated by GWT, and the styled gradients often break with updates.
