[Bug 92309] Box drawn around cursor in multiple 3D games

https://bugs.freedesktop.org/show_bug.cgi?id=92309 --- Comment #14 from Michel Dänzer --- Kamil is spot on. In particular, this means that the only way to encode a fully transparent pixel with premultiplied alpha is using (0, 0, 0, 0). Which is obviously not the case for the cursors on the atta

https://bugs.freedesktop.org/show_bug.cgi?id=92309 --- Comment #10 from Michel Dänzer --- Presumably the cursor isn't captured by apitrace because it's not rendered using OpenGL but uses the Xcursor* APIs. The artifacts are most likely due to the cursor image not using proper pre-mulitplied alph
