[Bug 42538] New: wined3d checks for a wrong GL_VENDOR in wined3d_guess_gl_vendor
https://bugs.winehq.org/show_bug.cgi?id=42538 Bug ID: 42538 Summary: wined3d checks for a wrong GL_VENDOR in wined3d_guess_gl_vendor Product: Wine Version: 2.2 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: trivial Priority: P2 Component: directx-d3d Assignee: wine-bugs(a)winehq.org Reporter: kamil.hornicek(a)reactos.org Distribution: --- The check >if (strstr(gl_vendor_string, "Mesa")< in wined3d/directx.c:1729 is wrong. Mesa presents itself with GL_VENDOR = "Brian Paul" and GL_RENDERER = "Mesa" as can be seen here: https://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/main/getstring.c#n115 Even though the code works because it later checks for GL_RENDERER == "Mesa" it still should be fixed. This was also previously fixed in wined3d_guess_card_vendor. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=42538 --- Comment #1 from Henri Verbeet <hverbeet(a)gmail.com> --- Is this causing an actual issue, or is this theoretical? It's true that the default implementation returns "Brian Paul"/"Mesa", but specific drivers can and do return their own strings for this. These strings have also changed between versions. -- 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.

It should read ReactOS. In our case it's not theoretical. Second - GL_VENDOR is set to "Brian Paul" since at least 2005 as you can see here https://cgit.freedesktop.org/mesa/mesa/commit/src/mesa/main/getstring.c?id=1... and you are already checking for the correct vendor in wined3d_guess_card_vendor. Would it be possible to add yet another check for GL_VENDOR == Brian Paul as was done in wined3d_guess_card_vendor a while ago? I realize that it doesn't really fix or improve anyting for you, but at least your code would be consistent. If not, thanks for your time anyway. -- 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.

Sure, adding an explicit check for GL_VENDOR "Brian Paul" is fine. I initially read the bug report as asking for the removal of the GL_VENDOR "Mesa" check, which I think would be more problematic. I'm still curious what set of GL_VENDOR and GL_RENDERER strings causes an issue here though. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
