Another quick update: in recent days we've gone from "blank white space" back to "incorrect stride corruption" in all documented cases (embedded browsers, help windows, MiniBrowser, etc).
I note in the dpkg logs, libglx-mesa0 got updated a few days ago, but unfortunately I'm unsure exactly when the change occurred so this is speculation on my part. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gtk+3.0 in Ubuntu. https://bugs.launchpad.net/bugs/1924251 Title: Embedded browser display corruption under Wayland on Pi desktop Status in gtk+3.0 package in Ubuntu: Confirmed Status in webkit2gtk package in Ubuntu: Confirmed Status in yelp package in Ubuntu: Confirmed Bug description: 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. 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.
