# Tigris v2.0.20

## 中文

- **Android 11 及更早的动态视频背景上，Dock 圆角不再发糊。** 视频继续在 Dock 下面播放。大约每 4 秒取一张小图，在 CPU 上做比较重的模糊，再按 Dock 的真实尺寸画圆角和亮边，大约 55% 不透明，所以正在动的画面能透出来。新的一层大约 700 毫秒淡入。内存很少或只有一两个核时改为约 10 秒一次。某次截图超过 150 毫秒就不再继续截，Dock 改成一层淡罩加亮边。滚动时的圆角同样按真实尺寸抗锯齿。Android 12 及以上的玻璃不变。
- 对应 [PR #78](https://github.com/lesnolie/Tigris/pull/78)，[#77](https://github.com/lesnolie/Tigris/issues/77)。Sony 9500G（Android 10）上的测试反馈：圆角不再发糊，背景视频不卡，其余功能正常。

## English

- **Sharp dock corners over moving video on Android 11 and older.** The video keeps playing under the dock. About every 4 seconds a small snapshot is blurred heavily on the CPU and drawn at about 55% opacity inside a rounded mask and rim at the dock's real size, so the moving picture shows through. A new frost fades in over about 700 ms. TVs with very little memory or only one or two cores wait about 10 seconds. A snapshot slower than 150 ms stops further copies and leaves a light veil plus the rim. The scrolled dock uses the same full-size anti-aliased corner. Android 12 and newer are unchanged.
- [PR #78](https://github.com/lesnolie/Tigris/pull/78), [#77](https://github.com/lesnolie/Tigris/issues/77). On a Sony 9500G running Android 10, the tester reported that the corners are no longer blurry, the background video does not stutter, and the rest of the app still works.

Android 9+, versionCode **27** (previously 26), same application ID and stable signing certificate. Upgrade in place with the matching Standard or Guard APK, including from the 2.0.17-test77b test build.
