http://bugs.winehq.org/show_bug.cgi?id=59299 Bug ID: 59299 Summary: Unreal Editor For HMM7 often hangs with a white window Product: Wine Version: 11.1 Hardware: x86-64 OS: MacOS Status: UNCONFIRMED Severity: normal Priority: P2 Component: d3d Assignee: wine-bugs@list.winehq.org Reporter: isakov-sl@bk.ru Created attachment 80236 --> http://bugs.winehq.org/attachment.cgi?id=80236 Sometime hang here I compiled Wine-11.1 from git and encounter a while window and spinning cursor i.e. hang. I found that wine-10.18 has no such behavior and so I can make bisection. The result ---------------------------------- sergey@iMac wine-11 % git bisect good 92f5d5bc7c8412924e7cb4f6f715ecc9c4e4dd13 is the first bad commit commit 92f5d5bc7c8412924e7cb4f6f715ecc9c4e4dd13 Author: Rémi Bernon <rbernon@codeweavers.com> Date: Thu Dec 18 20:40:04 2025 +0100 wined3d: Update the context DC from its swapchain if it changed. The context keeps a weak pointer to the swapchain, and the swapchain might be destroyed while are context still have a pointer to them. It's usually not causing issues because contexts will be refreshed with the new active swapchain before a present is executed. However, the new swapchain might be for the same window but might have a different DC. As we now borrow the DCs from the swapchains, we also need to check if the context DC needs to be updated.
