http://bugs.winehq.org/show_bug.cgi?id=59323 Bug ID: 59323 Summary: Guild Wars 2 crashes with Wine 11.1 and Winewayland enabled with dev builds of DXVK (newer than Jan 23rd) Product: Wine Version: 11.1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winewayland Assignee: wine-bugs(a)list.winehq.org Reporter: bwyazel(a)gmail.com Distribution: --- Running the latest development builds of DXVK directly from upstream, starting with the January 26th, 2026 builds, Guild Wars 2 will hard crash when paired with Wine 11.1 and using Winewayland. This bug has been reported to upstream here: https://github.com/doitsujin/dxvk/issues/5477 Likewise, it seems like it's possible that the crashes that I'm seeing are related to this commit here: https://bugs.winehq.org/show_bug.cgi?id=58143 The behavior that I'm seeing is as follows: Working: Wine 11.0 (with Wayland) with the latest DXVK commits Working: Wine 11.1 (without Wayland) with the latest DXVK commits Broken: Wine 11.1 (with Wayland) with the latest DXVK commits To trigger the bug with 100% certainty, within the game you need to open the player map and use the scroll wheel to zoom in and out. This will reliably cause the game to instantly crash. My system information: Arch Linux (updated as of Jan 27th, 2026) AMD Radeon 7900XT Mesa 25.3.4 (RADV) GNOME 49.3 (Wayland session) 3440x1440 165Hz monitor with VRR enabled Bottles 61.1 (Flathub) Wine 11.1 (Kronek) DXVK Dev Releases (Found here: https://github.com/doitsujin/dxvk/actions/workflows/artifacts.yml?query=bra…) Guild Wars 2 -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59257] New: RTF clipboard reads randomly chosen string (regression from wine 10)

Feb. 20, 2026

http://bugs.winehq.org/show_bug.cgi?id=59257 Bug ID: 59257 Summary: RTF clipboard reads randomly chosen string (regression from wine 10) Product: Wine Version: 11.0 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)list.winehq.org Reporter: ssb22(a)cam.ac.uk Distribution: --- After placing text on the X11 clipboard from Emacs 29.3 in Ubuntu 24.04 LTS and attempting to paste this into a Windows program that is set to read RTF clipboard when available, the Windows program alternately comes out with "emacs" or my full name or some other string, none of which are what I put on the clipboard. The code below minimally demonstrates the issue. Use `i686-w64-mingw32-gcc test.c` and `wine a.exe` after placing some text onto the clipboard from Emacs. This works correctly in WINE 10 but fails in WINE 11, potentially feeding randomly-chosen private strings to the Windows program instead (I was unable to figure out how it got my full name when this was not on the clipboard, but it's clearly somehow reading from some part of memory it shouldn't). ```c #include <windows.h> #include <stdio.h> int main() { UINT cfRtf = RegisterClipboardFormat(TEXT("Rich Text Format")); if (!OpenClipboard(NULL)) { printf("Failed to open clipboard\n"); return 1; } if (IsClipboardFormatAvailable(cfRtf)) { HANDLE hData = GetClipboardData(cfRtf); if (hData) { char* data = (char*)GlobalLock(hData); if (data) { printf("RTF clipboard contains: '%s'\n", data); GlobalUnlock(hData); } } else { printf("GetClipboardData failed\n"); } } else { printf("RTF format not available\n"); } CloseClipboard(); return 0; } ``` -- Do not reply to this email, post in Bugzilla using the above URL to reply.

For that, I'm using WineD3D in a modified version as of 11.0 and am building it with sanitizers enabled. For this, I'm reporting only one pixel format in GetPixelFormat. It being a hardcoded one, that will likely be present on most systems. (32-bit, 888, yada-yada). After the first frame is finished rendering, ASAN complains about line 596 being a heap use-after-free in the NVIDIA .so. Looking at what happens, in swapchain.c, the pixel_format at line 594, after "Presenting DC", is obtained from the context_gl->pixel_format field. pixel_format = &wined3d_adapter_gl(swapchain->device->adapter)->pixel_formats[context_gl->pixel_format]; This line seems suspicious to me, at the point where it gets set line 1907, the returned pixel format is directly the one from ChoosePixelFormat, which is 1 index-based according to documentation. This leads me to the assumption, that this is a mistake that has went overlooked, because most of the time more than one pixel format is returned. >From my understanding, the line should read: pixel_format = &wined3d_adapter_gl(swapchain->device->adapter)->pixel_formats[context_gl->pixel_format - 1]; ASAN doesn't complain about that part anymore afterwards.

[Bug 57435] New: D2D1GeometrySinc::AddArc() doesn't properly mark end of the figure segment

https://bugs.winehq.org/show_bug.cgi?id=57435 Bug ID: 57435 Summary: D2D1GeometrySinc::AddArc() doesn't properly mark end of the figure segment Product: Wine Version: 9.21 Hardware: x86-64 OS: Linux Status: NEW Keywords: source, testcase Severity: normal Priority: P2 Component: d2d Assignee: wine-bugs(a)winehq.org Reporter: dmitry(a)baikal.ru Distribution: --- Created attachment 77431 --> https://bugs.winehq.org/attachment.cgi?id=77431 Rounded rect under Wine If an application creates a rounded rect geometry manually using a sequence of calls ::AddLine() and ::AddArc() instead of ::CreateRoundedRectangleGeometry() then the created rectangle is distorted under Wine. While D2D1GeometrySinc::AddArc() is currently a stub, it tries to be smart and calls d2d_figure_add_vertex() to add a terminating arc point to the figure, however this doesn't work, and next call to ::AddLine() draws the line from the point where previous line was terminated instead of an added vertex, and this leads to drawing a distorted rectangle. A simple implementation of ::AddArc() that calculates points of two arc quadrants and calls d2d_geometry_outline_add_arc_quadrant() helper also suffers from the same problem: added arc quadrants don't seem to properly mark end of the figure segment. This seems to be caused by difference between how ::AddLines() and d2d_geometry_outline_add_line_segment() (used by d2d_rounded_rectangle_geometry_init() helper called from ::CreateRoundedRectangleGeometry()) create line segments. Attached test applications (source + binary) use both described above approaches: ::CreateRoundedRectangleGeometry() and ::AddLine() + ::AddArc().
