Bug ID: 53771 Summary: [QQ&WeChat&DingTalk] Window's edge decoration window is always on top Product: Wine Version: 7.12 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: user32 Assignee: wine-bugs@winehq.org Reporter: 399989567@qq.com Distribution: ---
My English is not good, so I hope to be forgiven if there are any poor wordings.
Nowadays, many windows are composed of two windows (e.g. QQ, WeChat, DingTalk), one window M is used to draw the user's interface, and one window S is used to modify the previous window (e.g. edge shading, etc.). The following diagram is provided for a better understanding of this issue: https://imgse.com/i/xJBuAs
I found that when many windows' applications run on wine, the window used to modify (window S) is always on top (even if it is covered by other linux applications, the window S is always on top and does not disappear).This affects the usage of the app.
I found this problem exists in wine7.12, know 7.18 also did not solve
