MusicPlayer.v2-Demo CPU 占用过高，到了40%

[archeng320]

CPU 是双核A7 1G主频， LCD使用是 fb，分辨率是1920*720，使用top 看CPU占用了40%。同一台机器，用QT软件，CPU才占用5%。请问，怎么优化CPU的使用率？

中间的转盘转动时会耗费cpu， 也可以看看你的平台是否支持drm模式，切换方法见awtk-linux-fb/readme

不平台支持drm模式。运行自带的demo1 ，cpu占用17%

./demo1 &

谢谢，我们查一下，可能是最近的版本修改的问题

[archeng320]

更新到新版软件后，简单的demo的cpu占用率降到1%，但是有动画的demo，如demo_animator ，CPU占用 17% ，不知道是否正常

[sohide]

正常的, 动画, 特别是旋转动画会占用cpu 47f26cbae14ed9a 本问题已修复, 请把awtk和awtk-linux-fb都更新到最新版本
