[Bug 27579] New: The appearance of uTorrent 3.0 torrents list is broken

http://bugs.winehq.org/show_bug.cgi?id=27579

Summary: The appearance of uTorrent 3.0 torrents list is broken
           Product: Wine
           Version: 1.3.22
          Platform: x86
               URL: http://download.utorrent.com/3.0/utorrent.exe
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Not only this part of µTorrent window is black, when you add a torrent to
download, its name and other attributes are hidden, when you try to switch the
current category from e.g. "Downloading" to "Seeding", this part of uTorrent
window will not be updated.

In short the appearance of uTorrent 3.0 under Wine is broken beyond being
usable.

Could be related -

Please check previous wine release to see if it's a regression.

It cannot be it, I'm using Wine 1.3.22 which doesn't include this commit.

It fails with wine 1.3.21 and 1.3.22 on Ubuntu Lucid 32 bits.

The problem isn't only the appearance, the preferences menu is unusable.
µTorrent hangs when I try to modify some preference or I try to modify the
visible columns in torrent list.

Can't confirm. I can open and modify preferences menu under:
 * 1.3.22 and wine-1.3.23-160-g38c13e5
 * Debian Squeeze 32bit
 * KDE 4.4.5

Have you tested changing several values and changing of tabs. 
To me works at start too but when I changed several options in different tabs,
at random time, µTorrent hangs.

Forget this.
It works in local, the problem appears when I manipulate µTorrent 3 from remote
server through Nomachine NX.

Unless someone amongst Wine developers gets interested in this bug, it may stay
unresolved for ... years.

However if you cannot live without it being resolved ASAP, you can offer a
financial incentive for this bug resolution or hire someone who can fix it.

For now you can stick with 2.2.1 which seems to work well, just avoid clicking
in the Files list for the torrent otherwise wine will crash.

Most likely unrelated to your problems. Did you try native comctl32?

Actually native comctl32 fixes this bugs report but adds a few other problems
(like the toolbar becomes totally invisible).

A quirk I noticed: setting enable_wine_hacks = false (mostly) fixes the main
torrent list, but breaks the file list in the add torrent dialog - the
checkboxes and filenames are missing. They can still be clicked, though.

uTorrent in current wine looks the same as in the attachment from comment 8.
There are several issues here:
1) the black background outside of the file list is caused by some
doublebuffering issue. Commenting out all doublebuffering code brings back
white background.
2) the black background of downloads is caused by custom draw not playing well
with LVS_EX_FULLROWSELECT. For some reason uTorrent returns CDRF_SKIPDEFAULT
when asked to paint the file name, which prevents painting background for the
entire row in wine's comctl32.
3) the invisible file name. I don't know why it happens. Either uTorrent paints
the item in incorrect place, or it doesn't paint it at all and returns
CDRF_SKIPDEFAULT in error.

Black background of torrent information is fixed by commit
80f70b5d85a3965d73840590bb5b38920b22fdc2.
Invisible file name is most likely a bug in uTorrent's wine hacks - when they
are disabled, file name shows up just fine. Someone should probably inform
uTorrent author(s) about that.
That leaves the doublebuffering issue. Any volunteers?

Are you here to SPAM of what?

Have you tried running uTorrent 3 at all? It's still largely broken and
unusable.

Comments calling to fix a particular bug are not how Wine development occurs.
If you are really interested you could hire someone and pay him to solve your
favorite bug. However even in this case there's no guarantee the fix will be
merged with Wine's code.

I used the link that is used on url box. It downloaded utorrent 3.4 something.
It looks horrible. I didnt see the issue mentioned here, but utorrent has now
web based adverts also the interface was somehow ugly.

Maybe we should change the dowload url?

I can hardly understand what you're talking about. The initial bug report is

Nothing has changed in regard to the current uTorrent version and Wine 1.9.1.

Disabling wine hacks inside uTorrent doesn't help either.

Version 2.2.1 build 25302 works beautifully though.

This bug has been partly fixed by patch 144692:
https://source.winehq.org/patches/data/144692

The numbers displayed in brackets in the left panel (indicating the total
number of torrents being downloaded, et cetera) should now automatically update
without having to manually click on them. This error was caused by the
comctl32/treeview code using realloc() instead of alloc(), meaning that the old
pointer was usually being returned (instead of a fresh new one) and thus the
pointer comparison incorrectly assumed that nothing had changed each time a new
torrent was added or removed, and hence the list did not update unless manually
refreshed.

However - the black screen error in the top panel still seems to persist. From
my own experience, this only takes effect when a new torrent is added (when
uTorrent is loaded for the first time without any torrents added, the display
updates normally as per uTorrent 2).

A temporary fix that seems to force the uTorrent upper panel to update is to
change the line "lps->fErase = erase;" in the BeginPaint() function within
dlls/user32/painting.c to "lps->fErase = 1;"

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.

hack to force it draw

Taking  [e-mail]  comment #37 I made a small hack for others to
use, on the top master that moved a lot of this code to win32u.

Other WM_ERASEBKGND instances of send_message don't use the result at all.
Maybe we shouldn't use it even in this case.

I made it so that send_erase intenrally return TRUE instead of forcing
ps->fErase to be TRUE in  NtUserBeginPaint.

Another possibility is to pass UPDATE_DELAYED_ERASE to send_erase in
NtUserBeginPaint, wtihout modfying the first condition flag the BOOL need_erase
= (flags & UPDATE_DELAYED_ERASE) != 0;
But the send_message was returning 0 so that assginemnt have to gone off.

I wonder if the partial cause is some sort of mishandling of the procedure call
(maybe it's return type) for some (or maybe just Background Erase), as this bug
involve wndproc overrides.

This also fix the same black box issue with Wrye Bash on the top of wine
staging (in particular th comctl32 patch setting it to version 6. Apparently
from other analysis in this report, that version make wxWidget (that WB use) to
inject a WndProc to that component (unsure if it's just this component override
that got added in the case or all  components) ). 
I will need to check wxWidget source

More info from wxWisget source.

When the comctl32.dll version is > 6 the listctrl component is assigned style
LVS_EX_DOUBLEBUFFER
and wxWidget make this call:
        // When using LVS_EX_DOUBLEBUFFER, we don't need to erase our
        // background and doing it only results in flicker.
        SetBackgroundStyle(wxBG_STYLE_PAINT);

wxWidget also install it's own wndproc that handle messages, and forward to the
builting procedure if a message is not handled. (it return false form the
internal message processing routine)

Now wxWidget as specific handling of WM_ERASEBKGND, then when the background
style is wxBG_STYLE_PAINT or wxBG_STYLE_TRANSPARENT it return True and doesn't
erase the background

It probably expect it to  be fully repainted in WM_PAINT
