I tested this patch on Wine Staging 11.5 and can confirm it fixes the issue. **Problem:** On KDE Plasma X11 sessions, when using window managed=y, Fusion 360's browser panel, Save as Mesh panel, and Comments panel are glitchy. Save and Open file dialog box are stuck under the main window. When using window managed=n, Fusion 360's browser panel, Save as Mesh panel, and Comments panel sink behind the main window and become inaccessible after being clicked. Save and Open file dialog box are stuck under the main window are fine there. The patch using window managed=y fixes all the mentionned bugs above. **Confirmed working on:** * Kubuntu 25.10, Wine Staging 11.5, NVIDIA RTX 4070, KDE Plasma X11 * Kubuntu 24.04.4 LTS, Wine Staging 11.5, AMD Ryzen 3500U Vega 8 APU, KDE Plasma X11 The patch applies cleanly to Wine 11.5 with no conflicts. Would be great to see this merged into mainline. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/2343#note_133251
