Emulator 28.1.5 Canary 发布了，目前可以在Canary 和 Dev channels 使用，此版本更新如下：
Project Marble:
Changed how the default window size of the emulator is calculated so as to fill more of the screen.
Some users were concerned that the previously smaller size was not changeable; it has always been the case that the emulator window can be resized by dragging near the corners, even if there is no window frame.
Decreased overhead of the OpenGL emulation driver on the host side to use less CPU per draw call.
Vulkan Support Check. The emulator now checks the host side Vulkan driver, querying the level of support for Vulkan features. This check is a preliminary step for further Vulkan support in the future, and should not interfere with normal operation.
If this check on startup ends up crashing or hanging the emulator, please tell us your OS and hardware GPU setup along with whether you are running the emulator with or without a display attached.
In a future version, we will be tracking metrics from this check.
