https://bugs.winehq.org/show_bug.cgi?id=48740 Bug ID: 48740 Summary: ConEmu is constantly loosing focus Product: Wine Version: 5.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)winehq.org Reporter: rpisl(a)seznam.cz Distribution: --- ConEmu is constantly loosing focus in the console window and also in the settings dialog. This behavior makes it unusable. Focus is set back after clicking by mouse but for only a few seconds. Tested on Wine 5.3 and Wine-Staging 5.3 with same behavior. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 48738] New: When running certain Batch files, my Wine cmd.exe reproducible crashes with "page fault on read access" or with "stack overflow in 32-bit code".

https://bugs.winehq.org/show_bug.cgi?id=48738 Bug ID: 48738 Summary: When running certain Batch files, my Wine cmd.exe reproducible crashes with "page fault on read access" or with "stack overflow in 32-bit code". Product: Wine Version: 5.3 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: cmd Assignee: wine-bugs(a)winehq.org Reporter: temp2004(a)freenet.de Distribution: --- Created attachment 66628 --> https://bugs.winehq.org/attachment.cgi?id=66628 Two batch files and the crashdump I think the problem is new since middle of last year, at least reproducible with Wine 5.2 and 5.3. Find attached two small batch files: they should set some environment variables and look for some directories, but they don't reach their end. At real Windows (also when running at VirtualBox) they work properly instead. Scenario: create a directory and store one.bat and two.bat into it. run: wineconsole one.bat If the problem occurs, Wine crashes immediately. ("wine: Unhandled page fault on read access to FFFFFFF0 at address F7D2D3AB (thread 01a8), starting debugger...") The behavior depends very much on the content of the batch files: adding commands or changing the variable's names may prevent it from crashing or may shift the crash to a different line. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 49142] New: Horizontal mouse scroll events (X11 buttons 6 and 7) should not be translated to back/forward events
by WineHQ Bugzilla Aug. 7, 2020

Aug. 7, 2020

https://bugs.winehq.org/show_bug.cgi?id=49142 Bug ID: 49142 Summary: Horizontal mouse scroll events (X11 buttons 6 and 7) should not be translated to back/forward events Product: Wine Version: unspecified Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)winehq.org Reporter: muzerakascooby(a)gmail.com Distribution: --- Wine translates X11 buttons 6 and 7 to back/forward events. While these historically were occasionally mapped to back/forward buttons on mice, nowadays the overwhelming standard is to use 6/7 exclusively for horizontal scrolling, and 8/9 for back and forward buttons (which wine also maps to these events). The existing behaviour makes some applications more painful than necessary to use on laptops with touchpads, as horizontal scrolling (a normally quite harmless activity) can be triggered quite easily by accident when scrolling vertically, causing back and forward events (which are considerably less harmless) to be sent. I understand that there has only been a standard in Windows for horizontal scrolling since Vista, so I understand if implementing this is unfeasible. But horizontal scroll events should NOT be translated into back/forward events. I believe the culprit to be mouse.c lines 77/78, 90/91, 103/104, and 116/117 (as of 7afa53c0f20aa40f0d13c81a7d20b523f62f99ab). -- Do not reply to this email, post in Bugzilla using the above URL to reply.

ConEmu flickers and scrolls randomly after console is filled with content. The problem is in the way wineconsole recalculates position and scrollbars in WCUSER_ComputePositions. (ConEmu runs wineconsole in background). -- 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.

[Bug 48495] New: XCP-ng Center v8.x (.NET 4.6 app) can't connect to server with self-signed certificate
by WineHQ Bugzilla Aug. 7, 2020

Aug. 7, 2020

https://bugs.winehq.org/show_bug.cgi?id=48495 Bug ID: 48495 Summary: XCP-ng Center v8.x (.NET 4.6 app) can't connect to server with self-signed certificate Product: Wine Version: 4.21 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: crypt32 Assignee: wine-bugs(a)winehq.org Reporter: imirkin(a)alum.mit.edu Distribution: --- Needless to say, this works fine on windows. The application requires the "dotnet462" winetricks verb to start, and see #48492 for ways to get past the splash screen. Installation msi available from https://github.com/xcp-ng/xenadmin/releases/download/v8.0.1.26/XCP-ng-Cente… . However once in the application, it can't actually connect. WINEDEBUG=trace+crypt,trace+chain shows the following happening over and over and over and over again: 0072:trace:crypt:CertVerifyCertificateChainPolicy (#0004, 0xbe571d0, 0xd7beb70, 0xd7beb30) 0072:trace:chain:dump_policy_para cbSize = 12 0072:trace:chain:dump_policy_para dwFlags = 00000010 0072:trace:chain:dump_policy_para pvExtraPolicyPara = 0xd7beb60 0072:trace:chain:dump_ssl_extra_chain_policy_para cbSize = 16 0072:trace:chain:dump_ssl_extra_chain_policy_para dwAuthType = 2 0072:trace:chain:dump_ssl_extra_chain_policy_para fdwChecks = 00000000 0072:trace:chain:dump_ssl_extra_chain_policy_para pwszServerName = L"<redacted>" 0072:trace:crypt:CertVerifyCertificateChainPolicy returning 1 (800b0109) 800b0109 = CERT_E_UNTRUSTEDROOT And indeed, it's a self-signed certificate, which isn't in the trusted list. However note that policy_para.dwFlags = 0x10 == CERT_CHAIN_POLICY_ALLOW_UNKNOWN_CA_FLAG . This is handled in verify_base_policy. However verify_ssl_policy only checks for the bit in extra_chain_policy_para.fdwChecks, which is empty here. The (.NET) application does the following: SslStream sslStream = new SslStream(stream, false, new RemoteCertificateValidationCallback(ValidateServerCertificate), null); Where the ValidateServerCertificate function = "return true". I suspect that the policy para's dwFlags should be respected by verify_ssl_policy even if fdwFlags isn't set... but my familiarity with these APIs extends to all of the past couple of hours ... an expert opinion would be quite welcome. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

Tested with AoE2 + expansions. NOTE: I'm not talking about the newer AoE2HD which supports windowed mode out of the box, it's the older versions that didn't support windowed mode at all. Newer windowed mode wrapper projects such as 'DxWnd' (https://github.com/DxWnd/DxWnd.reloaded) use more safe mechanisms (VirtualProtect) to make sure the vtables are actually writable. But again, it seems native DDraw has writable vtables. Regards -- Do not reply to this email, post in Bugzilla using the above URL to reply.
