gtk4-4.16.0

[Xi Ruoyao]

New minor version.

[Xi Ruoyao]

The upstream has switched the default from GL to Vulkan on Wayland. And to enable the Vulkan support (removing -D vulkan=disabled) we need glslc. As other google packages, building it makes a headache...

When I run GTK-4 apps with gtk-4.16.0 + Vulkan, the Intel Vulkan driver complains something like

MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:763: FINISHME: support YUV colorspace with DRM format modifiers
MESA-INTEL: warning: ../src/intel/vulkan/anv_formats.c:794: FINISHME: support more multi-planar formats with DRM modifiers

but nevertheless they seem running fine.

What version of mesa are you running? A grep of the mesa 24.2.2 only shows the YUV message in docs/relnotes/24.2.0.rst and no hits for the multi-planar message.

24.2.2.

When doing a grep we have to remove the FINISHME: part because the actual code is like:

anv_finishme("support YUV colorspace with DRM format modifiers");

i.e. the FINISHME: prefix is added by anv_finishme(). And the message gives where the message is: ../src/intel/vulkan/anv_formats.c:763. Here .. is the mesa source dir because we are building with meson setup ${OPTIONS} ...

I've not seen any negative effect so far despite these warnings.

[Bruce Dubbs]

Looking at the code, those are the only two anv_finishme() calls in that file. We could comment them out.

anv_finishme() is a macro in src/intel/vulkan/anv_private.h. It looks like a developer only type of message. We could effectively change that to a no-op if we want.

It's easier to suppress them with MESA_LOG_FILE=/dev/null at runtime.

4.16.0

Overview of Changes in 4.16.0, 09-06-2024
=========================================

Note: This release changes the default GSK renderer to be Vulkan,
on Wayland. Other platforms still use ngl. The intent of this change
is to use the best available platform APIs. You can still override
the renderer choice using the GSK_RENDERER environment variable.

We believe that most of the problems reported with the new renderers
during the 4.13 and 4.15 development cycles have been addressed by now.

But the new renderers and dmabuf support are using graphics drivers
in different ways than the old gl renderer, and trigger new driver bugs.
Therefore, it is recommended to use the latest mesa release (24.2)
with the new renderers.

* GtkScale:
 - Fix positioning of scale values

* GtkEmojiChooser:
 - Make Control-clicks work for the recent section

* GtkPopover:
 - Make sure focus lands on the right widget when cascading

* GtkSpinButton:
 - Disable Emoji input for numeric spin buttons

* GtkSingleSelection:
 - Implement unselect_all

* Accssibility:
 - Fix roles for radio buttons
 - Check if ATs are listening before exporting trees
 - Add a check for sandboxed accessibility bus
 - Fix handling of the error message relation
 - Turn criticals into debug messages
 - Set expanded states properly in menus

* CSS:
 - Fix a few issues on bigendian systems
 - Avoid a crash with relative colors

* GSK:
 - Use the right GL context when exporting textures
 - Don't let colors influence depth decisions
 - Allow uploading of mipmap levels when tiling textures

* GDK:
 - Update keysyms from libX11 1.8.10
 - Implement cpu-side mipmapping
 - Use a thread pool for color conversions and mipmapping

* Vulkan:
 - Fix drag surface offsets

* Wayland:
 - Fix a crash
 - Associate EGL windows with context later

* X11:
 - Fix initial EGL context creation
 - Fix a problem with GL context creation

* Broadway:
