** Description changed:

- On the hirsute Pi desktop, under a wayland session with the "full" KMS
- overlay enabled, and "kms-modifiers" present in the
- org.gnome.mutter/experimental-features, the body of a window containing
- an HTML renderer (e.g. help text or a login page) displays corruption.
+ On the jammy Pi desktop, under a wayland session, the body of a window
+ containing an HTML renderer (e.g. help text or a login page) displays
+ corruption.
  
  These reproduction cases may not be entirely reliable given that *some*
  pages appear to render correctly, but I'll include a couple in the hopes
  of making it reliably reproducible:
  
  1. Open the Lights Off game
  2. Select "Help" from the menu
  3. In the help window that appears, select any link
  
  "Basics", "Rules", and "Strategy" all reliably reproduce the issue for
  me, but "Help Translate" doesn't so you may need to click around some
  links until the corruption appears -- however, once it does even
  navigating back to the prior page which rendered happily now displays
  the same corruption.
  
  Another reproduction case:
  
  1. Open the Settings application
  2. Select the Online Applications option from the left
  3. Select the Google entry in the list
  4. The login window that appears always displays corruption for me
  
  The Microsoft option always reliably corrupts for me, but the Facebook
  one doesn't so again I wonder how reproducible this may be for others
  (might be worth trying several options if the first doesn't display
  corruption).
  
  The corruption appears in the form of "shredded" content as if a
  horizontal stride is set incorrectly somewhere, but only appears in the
  body of the window; the window decorations are unaffected. I'll attach a
  screenshot of the corrupted help window to illustrate.
