1. A concise explanation of the problem you're experiencing.
Rendering error when rorate or pan cesium view displaying point cloud tiles.
It didn't occur before doing the following:
Update cesium from 1.54 to 1.55.
Changed point cloud tile to doraco format.
Include draco_decorder.wasm etc.
It no longer occurs when clearing the browser cache.
Is there any other way to clear the browser cache?
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.
Sorry, I can't show code example. And there is no error log.
4. The Cesium version you're using, your operating system and browser.
There was a pull request to fix this that will be coming out with the next release in 1.57. You can wait until that comes out May 1 or try the current master branch in the Cesium repository and see if the error still occurs there.
It was consistently reproduced by rotating or panning even a little.
It was reproduced on most PCs that hold the cache before doing the listed updates.
We will update to 1.57 in May to see if similar errors occur.
Thanks for your help.
