Hi, All, When we tried to fix one issue of Conformance Test Suite (zbfunc.c), we found there was a mismatched bitmap cache with the z-buffer. This cache is used for bitmap drawn, and it keeps the drawn info such as positions/width/height. If the next drawn task with the same position && width && height, the cache will not be flushed. So if only the depth value for pixels is changed, the cache will hold on, and the z buffer cannot be updated either, which will cause some zbfunc tests failed. We got one possible fix for this issue as attached. Please have a review with it. And any comments are appreciated! Thanks!
