Package: libxcvt0 Version: 0.1.1-3 Severity: important X-Debbugs-Cc: dima@dimakrasner.com See https://gitlab.freedesktop.org/xorg/lib/libxcvt/-/merge_requests/9. The screenshot there is taken with jammy's xwayland 2:22.1.1-1 (running fullscreen, maximized by the compositor) and libxcvt0 0.1.1-3. This bug prevents applications from filling the screen when fullscreen, and can cause blurriness in applications that compensate for the missing 6x of width.
