[Bug 27579] The appearance of uTorrent 3.x torrents list is broken

It's also possible to force the uTorrent 3 window to redraw correctly by
preventing the program from assigning a custom Window Procedure routine to the
upper panel, which forces the original WndProc routine to be used instead, and
LISTVIEW_EraseBkgnd() to be automatically called upon resizing.

In the [ dlls/user32.c/WIN_SetWindowLong() ] routine, add the following three
lines beneath the "case GWLP_WNDPROC:" line in the "switch (offset)" section:-

char class_name[200];
GetClassNameA(hwnd, class_name, 200);
if (memcmp (class_name, "SysListView32", 13) == 0 ) {break;}

Note: When uTorrent 3 first launches (i.e. before a torrent is added), the
upper panel redraws correctly because it does not initially appear to be a
ListView window – possibly due to the presence of a sub-window in the main
panel which reads: "Go to Featured Content to get torrents."

uTorrent 2 does not seem to set a custom WndProc routine for the main panel
(and never features the "Featured Content" window), which seems to be why it
draws correctly (unlike uTorrent 3). A similar error can be generated in
uTorrent 2 by entering "return 1;" at the beginning of the [
dlls/comctl32/listview.c/LISTVIEW_EraseBkgnd() ] function; if ‘0' is returned
instead, then the ‘fErase' flag in [dlls/user32/painting.c/BeginPaint() ] seems
to get set, and the window redrawn.
