[Bug 1883742] Re: funky font rendering on kubuntu

[gregrwm]

** Description changed:

  The 3 screenshots are all of the same conversation in my gmail inbox.
  One screenshot was taken running Firefox Nightly on a Focal Ubuntu
  install, where the font rendering seems fine.  The other two screenshots
- were taken running Firefox Nightly on a Focal Kubuntu install.
+ were taken running Firefox Nightly on a Focal Kubuntu install where the
+ rendering is funky.
  
- Even on Kubuntu, the font spacing on my gmail inbox looks right on
- Chromium (Version 83.0.4103.61 Official Build snap 64-bit), but is funky
- (extra spaces within words) on Firefox Nightly, thus this was first
- reported as http://github.com/webcompat/web-bugs/issues/53474
+ This only happens on Kubuntu, eg running kubuntu-20.04.2.0-desktop-
+ amd64.iso live.  Lubuntu-20.04.2.0-desktop-amd64.iso live is fine, no
+ funky font rendering.
  
- In Firefox Nightly on Kubuntu, the font placement/spacing often shifts
- around, sometimes spuriously, and sometimes when interacting, for
- example when i tick or untick the conversation as in the the 2nd and 3rd
- screenshots.  Note how all the "t"'s move over in "Opportunities",
- "Youth", "item", and "interest".
+ Even on Kubuntu, when using Chromium (Version 83.0.4103.61 Official Build snap 64-bit), the font spacing on my gmail inbox looks fine, thus i first reported this as
+ http://github.com/webcompat/web-bugs/issues/53474
+ But they conclude it's not a Firefox issue.
+ 
+ The funky font rendering only happens with the combination of Kubuntu
+ (with all package updates as of 9/20) with either Firefox or Firefox
+ Nightly eg version 94.0a1 (2021-09-24) (64-bit).  Letters are often
+ mispositioned, jammed into the adjacent letter on one side and/or far
+ away from the adjacent letter on the other side.  And the font
+ placement/spacing often shifts around, sometimes spuriously, and
+ sometimes when interacting, for example when i tick or untick the gmail
+ conversation, as in the the 2nd and 3rd screenshots.  Note how all the
+ "t"'s move over in "Opportunities", "Youth", "item", and "interest".
