Just a quick note that running SimSig on Linux under the latest Wine versions 3.17 or 3.18 has a minor breakage with the scrollbars on the Failures tab of the Options window. Linux users should hold off updating to these versions for now. I have raised the bug with the Wine developers in their bug tracker as Mantis 46004.

I've just discovered that, rather more critically, this bug also impacts ground frame operation. :( This makes me much more likely to dig into the Wine source code myself to fix the issue rather than wait on the upstream devs to fix it themselves... Log in to reply |

Looking at the commit you bisected to, I wonder if maybe SimSig (either intentionally itself, or because Delphi’s GUI toolkit does it) might be subclassing the standard Windows scrollbar window class and registering a different message handler, which would result in the sanity check in SCROLL_GetInternalInfo failing for such scrollbars even though they are legitimate scrollbars? If I remember correctly from my Windows programming days I think subclassing window classes was possible. So, perhaps Wine needs to check for that situation.

If I remember correctly from my Windows programming days I think subclassing window classes was possible. So, perhaps Wine needs to check for that situation. I have no idea what Delphi does but it is certainly possible to change the windows procedure by calling SetWindowLongPtr() with GWLP_WNDPROC as argument 2.

Yep, the bug was in the subclassing. Testcases and patches have been written and will hopefully land for Wine 3.20.

The fix has landed in the Wine source tree and will be fixed with the Wine 3.20 release.
