It appears that some Wayland compositors don't always use a linear RGBA pixel format for their DRM planes. For example, KDE Plasma 5 can use a "30bit" ABGR
2:10:10:20format. Shadow Cast currently (and rather naively) assumes a format of ARGB8:8:8:8, which means frames are encoded incorrectly.The following still is taken from a H264 video captured on KDE Plasma 5...
For reference, the above video frame is displaying this image in the center of the screen...
