Hi, Recently I was trying to capture screen in wayland using kmsgrab and noticed that the output is mangled/tiled. When one does kmsgrab and hwdownload, as the data could be tiled many a times, I have implemented a simple cpu based detiling logic to convert them into linear layout, so that it is proper for use.
I have implemented logic to detile Intel legacy tile-X and tile-Y formats. Attached is the set of patches using git format-patch wrt the code which I did. Parallely I am also attaching a git diff master version which has all the changes as a single patch file. Hope this can help some people who may want to capture screen on a machine with Intel gpu. -- Keep ;-) HanishKVC
