- 当前 Bug 的表现（可附上截图）




- 预期表现
开发者工具中不draw，就不会生效，真机（安卓 mix2s Android9版本）中测试时发现开启draw不生效，关闭直接导出图片会生效


- 复现路径


- 提供一个最简复现 Demo
wx.canvasPutImageData({
canvasId: 'canvas1',
data: imgData.data,
x: 0,
y: 0,
width: width,
height: height,
success: function(res) {
console.log('log')
// ctx.draw(true, () => {
console.log('create img')
wx.canvasToTempFilePath({
x: 0,
y: 0,
width: width,
height: height,
destWidth: 3 * width,
destHeight: 3 * height,
canvasId: 'canvas1',
success: function(res) {
console.log(res)
},
fail: function(res) {},
complete: function(res) {},
}, that)
// })
},
fail: function(res) {},
complete: function(res) {},
})
