Summary: Color of the "text select" mouse pointer

Initial Comment:
This problem is reproduced easily with PuTTY, the popular 
SSH client for Windows. PuTTY is started in a remote 
desktop session, of course. The "text select" mouse cursor 
over a PuTTY window is black and thus hardly visible on the 
window's default black background if using rdesktop. The 
cursor is white, as it should be, if using MSTSC. Moreover, 
the mouse cursor becomes black or white if reconnecting to 
the same session with rdesktop or MSTSC, respectively.

In general, rdesktop always seems to use black color for 
the "text select" mouse pointer while MSTSC, as well as the 
regular Windows desktop, does something like logical NOT 
over the underlying pixels to get the pointer image on the 
screen. The latter approach ensures easily that the pointer 
is visible over any solid filling or pattern.

Versions used to reproduce the bug:
MS Windows Server 2003 SP1
rdesktop 1.4.1
PuTTY 0.58

Warren,

I really appreciate that this issue is remembered and understood.  Indeed,
it is deeper and more of an architectural one than I would anticipate back
when I submitted it.

Thank you!

Yar

Message:
This isn't really an rdesktop bug but a limitation of X.  (That's the short
answer - but there may be a workaround)

For performance, rdesktop is mapping windows cursors to X cursors.  RDP
servers transmit the actual bitmaps of the cursors (i.e. it doesn't say
"switch to I-beam cursor, it sends the I-beam cursor image over the
network).  Rdesktop creates an X cursor from that data.

The problem is that windows is capable of using "xor" pixels which change
based on the pixels underneath them.  X is not capable of this.  So you
can't simply map a windows cursor onto an X cursor.

There may be a workaround which would be to hide the X cursor and just
simulate a windows cursor right on the main surface.  I don't know what the
performance impact would be (might need to be an option on the cmd line)

A short term workaround might be to find a windows I-beam cursor that
isn't all black (or all white either, probably), or use putty with a
non-black background or something.

I'd like to bump this bug.  I've recently started using Putty over
rdesktop sessions, and the black on black I-beam cursor is killing my eyes.
 Windows XP here, although I'm sure it's a fairly generic issue.

Forgot to mention the versions I'm using:

MS Windows 2000 Professional
rdesktop 1.4.1 (compiled on Mac OS X 10.4.7)
Visual Basic 6

I am running into this problem as well.  I use a black background in
Visual Basic, 
and the text cursor (the I-beam) is black as well, making it hard to
select text or 
position the mouse on a line.  

Some sort of logical NOT makes sense here.

The modern datacenter depends on network connectivity to access resources
and provide services. The best practices for maximizing a physical server's
connectivity to a physical network are well understood - see how these
rules translate into the virtual world?
