I tried to send a HELP request to xorg-request but it disappeared without any trace as far as I can tell, so I'm not sure whether I can subscribe. If anyone sees this, _something_ got through, though.
There's a bug I've seen in various X servers. I *think* they're all derived from X.org code, and I suspect this is moderately widespread; I've seen it on recent Ubuntu, recent RaspOS, and old NetBSD. I wrote a tiny test (ftp.rodents-montreal.org:/mouse/misc/cursor-bug.c - also available over HTTP as well, though I'm not sure what Content-Type: it'll be served as) and people on NetBSD's tech-x11 report it on recent NetBSD as well, on some, but only some, hardware. The bug is that creating a pixmap cursor (a CreateCursor request) with a mask of None typically extends the source pixmap to the right with server-dependent data (typically background pixels) to a width such as 16 or 32 pixels. See the comment header on the test program for more. I wrote patches to fix this for two server versions (the ones that shipped with NetBSD 4.0.1/i386 and 5.2/amd64). I can certainly send those patches if anyone wants them; they are old, but if that part of ProcCreateCursor is unchanged since then they might be a useful starting point (though I do have low-to-negative confidence I got the code right for other architectures). /~\ The ASCII Mouse \ / Ribbon Campaign X Against HTML / \ Email! mo...@mojatatu.com
