https://bugs.winehq.org/show_bug.cgi?id=48088 Bug ID: 48088 Summary: DIB engine does not work on a 256-color X server Product: Wine Version: 1.5.13 Hardware: x86 OS: Linux Status: NEW Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)winehq.org Reporter: alexhenrie24(a)gmail.com Distribution: --- Created attachment 65646 --> https://bugs.winehq.org/attachment.cgi?id=65646 Regedit in Xephyr To reproduce, run `Xephyr :1 -ac -screen 800x600x8` in one terminal window and `DISPLAY=:1 wine regedit` in another. The window colors are positively psychedelic. A regression test on a Debian 6.0 Squeeze virtual machine revealed: 33ac850c80634c891b0c157bbffa612f70954a40 is the first bad commit commit 33ac850c80634c891b0c157bbffa612f70954a40 Author: Alexandre Julliard <julliard(a)winehq.org> Date: Thu Sep 6 12:39:34 2012 +0200 winex11: Use window surfaces for rendering top-level windows.

[Bug 53572] New: Misbehaving system tray icons on Wayland session
by WineHQ Bugzilla Aug. 5, 2026

Aug. 5, 2026

https://bugs.winehq.org/show_bug.cgi?id=53572 Bug ID: 53572 Summary: Misbehaving system tray icons on Wayland session Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: ryu.ketsueki(a)outlook.com Distribution: --- This is a bit more complex to explain, as this happens more specifically if you are on a Wayland session desktop. May be a duplicate of 48550 but I decided to drop more of what I could find out. Previously this was reported on KDE's Bugzilla as well and currently there may not be an easy fix on Plasma's side for a number of reasons. First, it may be using a deprecated proxy, XEmbedSNIProxy, which may be supported in X11 in a "very hacky way" as described in the bug report and it is completely unsupported in Wayland. Other apps also have this issue, like Anydesk, but Wine may be used for a lot more so it is more common to see those around. What happens is that, while the icon may appear on the tray, the "interactible" part of the icon is usually on the top left corner of the screen. And if there are many tray icons, only one can be interacted with. The icon itself on the tray is completely static and cannot be interacted with. Gnome does not have a system tray by default, requiring the user to install one through extensions. Every other desktop environment, however, does have a native system tray. Currently, KDE Plasma in the Wayland session is where this issue can be replicated, although I imagine other Wayland implementations such as Sway may also work. There is a known workaround but it is not perfect. Essentially involves terminating the XEmbedSNIProxy process and bringing the tray icons from there into a window with the wmsystemtray command. It is very hacky and far from ideal. If something can be done on Wine's side to try sorting this out, it would greatly improve its usability on Wayland, even without a native Wayland driver. Perhaps a new proxy that works both on X11 and Wayland can replace this old one? -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59018] New: Font artifacts on glyphs with overhangs
by WineHQ Bugzilla Aug. 4, 2026

Aug. 4, 2026

http://bugs.winehq.org/show_bug.cgi?id=59018 Bug ID: 59018 Summary: Font artifacts on glyphs with overhangs Product: Wine Version: 10.17 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: trivial Priority: P2 Component: win32u Assignee: wine-bugs(a)list.winehq.org Reporter: gamelaster(a)outlook.com Distribution: --- Created attachment 79757 --> http://bugs.winehq.org/attachment.cgi?id=79757 Images of the issue + PoC patch In the game MTA San Andreas (multiplayer modification for GTA San Andreas), in game chat and other parts using relevant API, some glyphs have leftover artifacts (images in attachment). ---------- User vahook from MTA:SA community was so kind that he investigated this issue and found the root cause, with hacky PoC fix provided. Quoting his explanation: >> The DrawText methods in Microsoft's d3dx9 implementation expect the ExtTextOut functions in GDI to opaque overhangs as well (TTF glyphs with a negative abcC value) when invoked with the ETO_OPAQUE option, as DrawText will use abcA + abcB as the glyph width when copying the rasterized glyphs from a (reused) temporary buffer to a texture. However, the current implementation in NtGdiExtTextOutW opaques out an abcA + abcB + abcC wide box, meaning the background behind overhangs won't be cleared, resulting in artifacts in the font texture from previously rasterized glyphs. In the attachment archive, there are images of the bug, also with image of PoC fix applied. PoC Fix patch is there as well. Additionally, there is font texture dump from the game, which shows that the artifacts are present in the texture. Vahook provided reproduction code as well, which I modified a bit to forcefully use d3dx9_42.dll for successful reproduction. The code can be found here: https://github.com/gamelaster/wine-gdi-font-artifact-repro with prebuilt binaries (built by me) available to be downloaded here: https://github.com/gamelaster/wine-gdi-font-artifact-repro/releases/tag/v1.… . -- Do not reply to this email, post in Bugzilla using the above URL to reply.
