[Bug 59591] New: Total Commander brief view jumps upward after rename due to inconsistent top_item clamping in comctl32_v6 listbox
by WineHQ Bugzilla April 14, 2026

April 14, 2026

http://bugs.winehq.org/show_bug.cgi?id=59591 Bug ID: 59591 Summary: Total Commander brief view jumps upward after rename due to inconsistent top_item clamping in comctl32_v6 listbox Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: comctl32 Assignee: wine-bugs(a)list.winehq.org Reporter: lldmakhbfcrmqyluns(a)nesopf.com Distribution: --- Reproduced with Wine devel 11.4 on Kubuntu 25.10 using Total Commander in brief view. Steps to reproduce: 1. Start Total Commander. 2. Open a directory with enough files to make the brief view span multiple columns. 3. Switch the panel to brief view. 4. Scroll to the bottom / end of the file list. 5. Rename the last file (Enter) or otherwise trigger a content refresh. 6. Observe that the panel jumps upward instead of keeping the previous scroll position. Expected result: The panel should keep the same visible position after the rename / redraw. Actual result: The top item is moved upwards after the redraw. Investigation: The affected control is not user32 listbox but the comctl32_v6 listbox implementation in: dlls/comctl32_v6/listbox.c The problem is that top_item is clamped inconsistently in two different code paths: 1. LISTBOX_SetTopItem() clamps top_item via: LISTBOX_GetMaxTopIndex( descr ) 2. LISTBOX_SetRedraw() later reclamps it via: descr->nb_items - descr->page_size In brief / multi-column listbox mode these two values are not equivalent. In the failing case I traced, LISTBOX_SetTopItem() restored: top_item = 140 for a list with: nb_items = 157 Later LISTBOX_SetRedraw() reclamped the same listbox to: top_item = 122 That secondary clamp caused the visible upward jump. Proposed fix: Use LISTBOX_GetMaxTopIndex( descr ) in LISTBOX_SetRedraw() as well, so both code paths use the same limit. Patch: diff --git a/dlls/comctl32_v6/listbox.c b/dlls/comctl32_v6/listbox.c index 7dec0e2d999..d2029cca434 100644 --- a/dlls/comctl32_v6/listbox.c +++ b/dlls/comctl32_v6/listbox.c @@ -730,8 +730,7 @@ static void LISTBOX_SetRedraw( LB_DESCR *descr, BOOL on ) InvalidateRect(descr->self, NULL, TRUE); if ((descr->top_item + descr->page_size) > descr->nb_items) { /* reset top of page if less than number of items/page */ - descr->top_item = descr->nb_items - descr->page_size; - if (descr->top_item < 0) descr->top_item = 0; + descr->top_item = LISTBOX_GetMaxTopIndex( descr ); } descr->style &= ~LBS_DISPLAYCHANGED; } This fixes the issue locally for me: after rebuilding and replacing comctl32_v6.dll, the panel no longer jumps upward after rename/refresh in brief view. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59532] New: Integer underflow in uniscribe implementation
by WineHQ Bugzilla April 14, 2026

April 14, 2026

http://bugs.winehq.org/show_bug.cgi?id=59532 Bug ID: 59532 Summary: Integer underflow in uniscribe implementation Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdi32 Assignee: wine-bugs(a)list.winehq.org Reporter: dsf190(a)me.com Distribution: --- Created attachment 80567 --> http://bugs.winehq.org/attachment.cgi?id=80567 segfault recorded by gdb https://github.com/ValveSoftware/Proton/issues/58#issuecomment-4040483961 Two example strings to cause this behavior are: @ฺxฺ $ำำx In gdi32/uniscribe/opentype.c, GPOS_apply_MarkToMark can underflow and cause an out of bounds read. If we try to run @ฺxฺ through, ScriptItemize (usp10.c) will break the string into 2 runs, one containing latin "x" and one containing the thai marks. See this line from GPOS_apply_MarkToMark: mark2_index = GSUB_is_glyph_covered((const BYTE*)mmpf1+offset, glyphs[glyph_index - write_dir]); When the run containing only the thai marks is passed here, the glyph_index (unsigned int) is evaluated to 0, and since thai is a LTR language, write_dir (signed int) is set to 1, resulting in 0 (unsigned) - 1 (signed). Since the 0 is unsigned the result would be an underflow and the program trying to evaluate glyphs[4294967295], causing the segfault in the attachment. It's likely that GPOS_apply_MarkToBase and GPOS_apply_MarkToLigature have similar assumptions that marks will never be alone in a run and/or set to the 0th position of the run's array. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59396] New: Tabbed UI in proprietary IDE broken after update – tabs are shown as separate windows
by WineHQ Bugzilla April 14, 2026

April 14, 2026

http://bugs.winehq.org/show_bug.cgi?id=59396 Bug ID: 59396 Summary: Tabbed UI in proprietary IDE broken after update – tabs are shown as separate windows Product: Wine Version: 11.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: Wagner.a18(a)yahoo.com Distribution: --- Since a recent update of a proprietary Windows-based IDE from my automation/control system vendor, the tabbed user interface no longer works correctly when running under Wine. Previously, the IDE displayed its editors and views as tabs within a single main window (similar to applications like Visual Studio Code). After the update, these tabs are now opened as separate top-level windows instead of being embedded as tabs in the main application window. This behavior only occurs when running the application with Wine. On native Windows systems, the IDE still behaves correctly and shows tabs as expected. Expected behavior: Editors and views should be displayed as tabs within the main IDE window, as before the update. Actual behavior: Each tab is opened as an individual window, breaking the intended tabbed workflow and making the IDE difficult to use. Regression: Yes. The tabbed interface worked correctly with earlier versions of the IDE under Wine. The issue appeared immediately after the vendor updated the application. Additional notes: The application is proprietary, so source code is not available. The issue seems related to how the updated IDE handles tabbed/docked windows or window embedding under Wine. Environment: Wine version: v11.1 Wine architecture: win64 / win32 Distribution: arch linux Desktop environment / window manager: kde plasma Application version: proprietary ide for control systems -- Do not reply to this email, post in Bugzilla using the above URL to reply.
