[Bug 59810] New: Buffered paint alpha/clear operations are missing
by WineHQ Bugzilla May 31, 2026

May 31, 2026

http://bugs.winehq.org/show_bug.cgi?id=59810 Bug ID: 59810 Summary: Buffered paint alpha/clear operations are missing Product: Wine Version: 11.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: uxtheme Assignee: wine-bugs(a)list.winehq.org Reporter: juan3(a)yandex.com Distribution: --- Applications using the buffered paint API can fail to render themed/translucent controls correctly because Wine does not perform the clear and alpha operations requested through BufferedPaintClear() and BufferedPaintSetAlpha(). These calls are used after BeginBufferedPaint() to prepare or adjust the backing buffer before EndBufferedPaint() copies the result to the target DC. On Windows, callers can clear a sub-rectangle of the paint buffer and apply a uniform alpha value to a sub-rectangle. Wine currently leaves those operations ineffective. Expected behavior: - BufferedPaintClear(buffer, NULL) clears the whole buffered paint area. - BufferedPaintClear(buffer, rect) clears the requested rectangle, clipped to the buffer. - BufferedPaintSetAlpha(buffer, NULL, alpha) applies alpha to the whole buffered paint area. - BufferedPaintSetAlpha(buffer, rect, alpha) applies alpha to the requested rectangle, clipped to the buffer. - Empty rectangles should succeed without changing pixels. Impact: Applications that depend on these operations may leave stale pixels in the buffered paint surface, lose expected transparency, or draw themed controls with incorrect backgrounds/alpha. One possible implementation direction would be to update the DIB-backed buffer directly for these operations, clipping the requested rectangle to the buffer bounds. For non-DIB-backed buffers, BufferedPaintClear() could clear through the memory DC. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59809] New: XF86VidModeSetGamma BadValue X error can terminate process
by WineHQ Bugzilla May 31, 2026

May 31, 2026

http://bugs.winehq.org/show_bug.cgi?id=59809 Bug ID: 59809 Summary: XF86VidModeSetGamma BadValue X error can terminate process Product: Wine Version: 11.10 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)list.winehq.org Reporter: juan3(a)yandex.com Distribution: --- XF86VidModeSetGamma may raise a BadValue X error for out-of-range gamma values. In winex11.drv, X11DRV_XF86VM_SetGamma() calls pXF86VidModeSetGamma() without wrapping the request in Wine's X error handling path. Other XF86VidMode requests in this area use X11DRV_expect_error() / X11DRV_check_error(). Without the guard, the X error can escape to Xlib's default handler and terminate the process. Observed issue: - X Error of failed request: BadValue (integer parameter out of range for operation) - Major opcode: XFree86-VidModeExtension - Minor opcode: XF86VidModeSetGamma Expected behavior: Wine should handle the X error and return failure from the gamma call instead of allowing the process to terminate. One possible fix would be to wrap pXF86VidModeSetGamma() with X11DRV_expect_error(gdi_display, XVidModeErrorHandler, NULL), synchronize when needed, check X11DRV_check_error(), and return FALSE on X errors. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=59808 Bug ID: 59808 Summary: Windows Form with ToolStripMenuItem closes program when selected in Bottles running in Linux Mint. Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: david.hine(a)outlook.com Distribution: --- I am writing my own programs in Visual Studio 2026 (Windows 11) to be used in a Bottles environment in Linux Mint. I am using the ToolStripMenu (menuStrip1 from the ToolBox). My programs compiled using .net 7.00 & before work ok in Bottles when the menu item is selected, but any .net releases after .net 7.00 cause the application to close. As .net 7.00 is no longer supported this will cause a future problem for me. The Bottles version is 64.1. Linux Mint version 22.3 Zena. I attempted to report the problem to Bottles, but their web page tells me to report Windows application problems to Wine or Proton. I hope you can help in this matter. Thank you. -- Do not reply to this email, post in Bugzilla using the above URL to reply. You are receiving this mail because: You are watching all bug changes.

The layering for that, seems to be identical to how it is for character-related graphics: in front of everything other than the gauges at the bottom, input-display, and menu. In the character-selection-menu, the screen seems to be brightened according to the transparency of the hovering weapons of certain characters, while those are supposed to be visible. With Wine 11.0 and 11.9: The visual effects are invisible, and do not brighten the screen. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59680] New: Path of Exile: font rendering related crash

Sadly I don't know how to run it with Wine alone since it's a game on Steam and is, therefore, configured to run with Proton. All steps below are based on Proton Experimental. How to reproduce: 1. Copy that character above. 2. Open Path of Exile with any Proton version that can run the game. 3. Log in with any character. 3a. Create one in any league if you don't have one. 4. Open chat (Enter key). 5. Paste character into chat. 6. Game crashes. Additional information @dsf3449 on GitHub has great information on what is causing this problem, I hope this can be of help: https://github.com/ValveSoftware/Proton/issues/58#issuecomment-4040483961 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
