Log from first bad commit with most warnings enabled

I'm running with "Emulate a virtual desktop" active.  I can start ChessBase 18
from the command line with `WINEDEBUG="-warn+all,warn-dpa" wine start
"C:\Program Files\ChessBase\CBase18\CBase18.exe"` in a 64-bit prefix.  The
application launches as usual, but after a few seconds, it stops responding to
the mouse altogether.  The CBase18.exe process consumes around 200% CPU as
shown in `top` when this situation occurs.  The log output does show new log
entries when I focus or unfocus the virtual-desktop window, but otherwise, it
does not typically appear to be logging anything.  I then stop the process from
the command line with, for instance, `killall CBase18.exe`.

I will attach a log from the first bad commit and, shortly thereafter, the last
good commit.
