+Gamescope compatibility binary
+================================
+
+gamescope-3.16.20-ubuntu26.04-amd64 is an isolated compatibility build for
+Ubuntu 26.04 amd64. The launcher uses it only when the installed system
+Gamescope reports version 3.16.20 and the binary passes its embedded SHA-256
+check. It never replaces /usr/games/gamescope.
+
+Source package:
+  Ubuntu gamescope 3.16.20+ds-1
+  gamescope_3.16.20+ds.orig.tar.xz
+  SHA-256 a27984fdab2bbfe353efc772de214ae88cccab07c4507747ed4b7f063b2faa0e

+The source changes are:
+
+  gamescope-wayland-letterbox-backing.patch
+    Backports upstream commit 66450376038864700f9b4721343b4d15b29c4198
+    ("Use a backing surface for letter-boxing"). It fixes direct Wayland
+    output when a unity-scaled game surface has a nonzero letterbox offset.
+
+  gamescope-wayland-libdecor-input-scope.patch
+    Keeps libdecor titlebar and resize-border button events out of the nested
+    application while preserving complete button sequences that begin on the
+    game surface. This prevents a decoration operation from leaving the game
+    with a permanently held mouse button. It addresses the behavior tracked
+    at https://github.com/ValveSoftware/gamescope/issues/2299.
+
+  gamescope-lazy-output-images.patch
+    Backports upstream commit e383171ff1c0f7b5b37f05f2bb67f7c5282b087f
+    ("rendervulkan: make the shared output images on first use"). Direct
+    Wayland frames no longer allocate six output-sized Vulkan images at every
+    intermediate host-window size.
+
+  gamescope-wayland-live-resize.patch
+    Skips the remaining device-idle wait and transparent fallback-image rebuild
+    when direct Wayland presentation has no live output images. Full-composition
+    frames still allocate correctly sized images on demand.
+
+  gamescope-keep-nested-windows-visible.patch
+    Honors PTLINUX_GAMESCOPE_KEEP_WINDOWS_VISIBLE by rejecting the game's
+    login-transition iconify request. The outer desktop window retains its
+    normal size and visibility while host minimize and focus remain untouched.

+From: PT Linux Launcher maintainers
+Subject: Keep the nested game window visible during its login transition
+
+PristonTale replaces its startup presentation while entering the login screen
+and asks the nested X11 window manager to mark the game window iconic. Gamescope
+3.16.20 acknowledges that request by publishing IconicState even though the
+surface stays mapped. Wine then hides or resizes the client, which also changes
+the outer Gamescope presentation.
+
+When the launcher opts in through PTLINUX_GAMESCOPE_KEEP_WINDOWS_VISIBLE, keep
+the nested client in NormalState. This is scoped to the launcher environment;
+Gamescope retains its upstream behavior for every other invocation. Desktop
+minimize and focus operate on the outer Wayland window and remain unaffected.

+
+Backport the upstream lazy-allocation change to Gamescope 3.16.20. Native
+Wayland presentation normally sends the game's DMA-BUF directly to the host
+compositor, so allocating six output-sized Vulkan images at startup and after

+Subject: Keep client-side decoration clicks out of nested applications
+Bug: https://github.com/ValveSoftware/gamescope/issues/2299
+Forwarded: https://github.com/ValveSoftware/gamescope/issues/2299
+
+On compositors without xdg-decoration support, libdecor creates client-side
+surfaces owned by the Gamescope Wayland connection. Pointer button callbacks
+for those titlebar and resize surfaces consequently also reach Gamescope's
+input thread. Forwarding a decoration press to the nested application can
+leave its button permanently held because libdecor consumes the matching
+release while performing a move, resize, or maximize operation.
+
+Only begin nested button sequences while the pointer is over Gamescope's
+actual toplevel surface. Track those presses so their releases are delivered
+even if the pointer or keyboard focus changes during a game-originated drag.

+From: PT Linux Launcher maintainers
+Subject: Avoid idle waits for direct Wayland resize configures
+
+The lazy-output-images backport leaves no shared output images allocated while
+Gamescope is presenting the game directly as Wayland planes. A host-window
+configure nevertheless calls vulkan_remake_output_images(), whose unconditional
+device-idle wait and output-sized blank-texture recreation stall the compositor
+thread for every intermediate drag size.
+
+Wait only when an output or screenshot image actually exists. The transparent
+fallback texture is unused by the non-session Wayland backend, so retain it
+across Wayland size changes; session backends preserve the existing recreation
+behavior. If a frame later requires full composition, the lazy allocation path
+creates correctly sized output images before rendering it.
