 ## Wallpaper & Colortheme
 
 - [WallReel](https://github.com/Uyanide/WallReel): an Image Carousel implemented with QtQuick to browse and set wallpapers from.
 - [change-colortheme](./config/scripts/.local/scripts/change-colortheme): script that extract colors from the current wallpaper and generate a catppuccin color scheme accordingly.
 - [backgrounds](https://github.com/Uyanide/backgrounds) collection for personal use (mostly waifus).

+
+The wallpaper will be automatically blurred when there is a window in focus, which is implemented in the [wallpaper-daemon](https://github.com/Uyanide/dotfiles/blob/main/.scripts/wallpaper-daemon) script.

+This feature is only enabled in Niri. Swww also manages wallpapers of the Hyprland setup, yet only in the regular way.

+## Wallpaper & Colortheme
+
+The most suitable primary color (or so-called flavor) will be chosen from the [Catppuccin Mocha](https://catppuccin.com/palette/) palette and applied to various apps automatically after changing wallpaper. And also:
+
+- [wallpaper-chooser](https://github.com/Uyanide/Wallpaper_Chooser) to select wallpaper, which implements an Image Carousel with Qt Widgets.

+## 问题
+
+### VapourSynth 破坏性更新
+
+> Tue May 5 09:08:30 CEST 2026
+
+- `extra/vapoursynth` 包更新至 75 版本后 (此问题其实是 R74 引入的, 但他们似乎跳过了 R74 直接在近几天更新至 R75), vsscript 库文件符号链接关系如下:
+  - `/usr/lib/libvapoursynth-script.so` -> `python3.14/site-packages/vapoursynth/libvsscript.so`
+  - `/usr/lib/libvapoursynth-script.so.0` -> `python3.14/site-packages/vapoursynth/libvsscript.so`
+
+  这导致 ldconfig 根据 SONAME 字段建立的缓存条目变化, 例如从 `libvapoursynth-script.so.0 (libc,x86-64) => /usr/lib/libvapoursynth-script.so.0` 变为 `libvsscript.so (libc6,x86-64) => /usr/lib/libvsscript.so`, 可能会使其他未能重新链接的程序找不到对应库.
+
+  但该问题影响范围比较有限, 因为动态库并不完全根据 ldconfig 缓存条目加载 —— 如果文件名完全匹配也能正确加载, 毕竟 `/usr/lib/libvapoursynth-script.so.0` 仍然存在.
+
+- 同时, 插件目录也从 `/usr/lib/vapoursynth/` 改为 `/usr/lib/python3.14/site-packages/vapoursynth/plugins/`, 很多包未能及时更新插件安装路径, 导致 vapoursynth 插件丢失.
+
+  extra 仓库中的 vapoursynth-plugin-\* 包均已改为类似如下动态查找插件安装路径的方式:
+
+  ```bash
+  install -Dm 755 libxxx.so -t "${pkgdir}"/$(python -c 'import vapoursynth;print(vapoursynth.get_plugin_dir())')/
+  ```
+
+  所以不会出问题. 主要影响范围是打包者或上游硬编码插件安装路径为 `/usr/lib/vapoursynth` 的包, 其中包括少数 extra 仓库的包如 `extra/ffms2` 和众多 AUR 包.
+
+- vapoursynth 不再在编译器 link libpython, 而必须在加载 libvsscript.so 时选择 python. 选哪个 python 由 `$HOME/.config/vapoursynth/vapoursynth.toml` 维护的映射关系决定, 格式类似:
+
+  ```toml
+  "/usr/lib/python3.14/site-packages/vapoursynth/libvsscript.so" = ["/usr/bin/python","/usr/lib/libpython3.14.so.1.0"]
+  ```
+
+  可以运行 `vapoursynth config` 自动更新.
+
+  然而, 上文提到过新的 libvsscript.so 的 ldconfig 条目是 `libvsscript.so (libc6,x86-64) => /usr/lib/libvsscript.so`, 而 `vapoursynth config` 只会在 `vapoursynth.toml` 写入 `/usr/lib/python3.14/site-packages/vapoursynth/libvsscript.so` 的条目. 此时, 如果加载 libvsscript.so, 会从 ldconfig 拿到 `/usr/lib/libvsscript.so`，而 vapoursynth 在拿到此路径后不解 symlink, 查 `vapoursynth.toml` 时和任何条目都对不上, 导致加载失败. 报错类似:
+
+  ```
+  Python executable and library path couldn't be determined despite automatic configuration. Run `vapoursynth config` to set it for this Python installation and then try again.
+  ```
+
+  临时修复方式为在 `$HOME/.config/vapoursynth/vapoursynth.toml` 里手动加上针对 `/usr/lib/libvsscript.so` 符号链接的条目:
+
+  ```toml
+  "/usr/lib/libvsscript.so" = ["/usr/bin/python","/usr/lib/libpython3.14.so.1.0"]
+  ```
+
+  如果运行 vapoursynth 此次更新前构建并链接的程序, 可能同样需要为 `/usr/lib/libvapoursynth-script.so.0` 准备对应条目:
+
+  ```toml
+  "/usr/lib/libvapoursynth-script.so.0" = ["/usr/bin/python","/usr/lib/libpython3.14.so.1.0"]
+  ```
+
+  影响范围为所有动态链接 vapoursynth 的二进制文件.
+
+### CUDA 13.2 不兼容 GCC 16.1
+
+> Mon May 4 15:39:17 CEST 2026
+
+nvcc 和 gcc 兼容问题的历史重演. 随 GCC 16.1 发布, 以前用 GCC 15.2 能够编译的 CUDA 包会报一堆错误, 影响范围非常大.
+
+解决方法为装 gcc15 等旧版本工具链, 并修改编译流程使 nvcc 使用指定编译器. 例如对于部分 Makefile:
+
+```makefile
+CUDA_CCBIN ?=
+cudaccbin = $(if $(CUDA_CCBIN),-ccbin $(CUDA_CCBIN),)
+
+...
+
+nvcc $(cudaccbin) ...
+```
+
+但这样会带来一个问题: `gcc15` 是 AUR 包, 需要编译. 而这并不会是一个很愉快的过程. 除去超大的仓库体积, 超长时间的编译测试和超高的资源占用外, 过程中还可能会因为各种问题失败, 修复问题后可能还需要从头再来, 成本过高.
+
+但好在 cachyos 有打包 `gcc14` 二进制包, 因此再降一个版本即可绕过编译过程. 但 AUR 上的众多打包者应该还是会选择 `gcc15`, 因此在有仓库打包 `gcc15` 二进制包或 NVIDIA 更新 CUDA 支持 GCC 16 之前, 几乎所有涉及 CUDA 的包仍然需要手动修改 PKGBUILD 构建.
+
+另外还有几个可选方案:
+
+- 可以用 clang++ 代替 nvcc, 但支持程度似乎有限 (`clang++: warning: CUDA version is newer than the latest partially supported version 12.9 [-Wunknown-cuda-version]`), 且对于部分已经在使用 nvcc 构建的项目可能需要较大幅度地修改编译参数和流程, 实用价值不高.
