[Bug 37052] New: WM_TRANSIENT_FOR occasionally contains unmapped windows
http://bugs.winehq.org/show_bug.cgi?id=37052 Bug ID: 37052 Summary: WM_TRANSIENT_FOR occasionally contains unmapped windows Product: Wine Version: unspecified Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: winex11.drv Assignee: wine-bugs(a)winehq.org Reporter: jstpierre(a)mecheye.net While debugging a focus management issue, I found that Wine creates an odd arrangement of WM_TRANSIENT_FOR windows. I assume this is the behavior of the Windows app. It's reproducible with the first screen of this installer: http://files01.techspot.com/temp/Unigine-Heaven-40.exe Wine is creating three windows: the actual installer window (A), a secondary window (B) as its owner, and a third window (C), invisible owner as B's owner. The issue is that while A and C are mapped, the intermediate window, B, is not, and thus the WM_TRANSIENT_FOR is invalid and ignored by window managers. This has the when activating the invisible owner C from the taskbar or similar, A is not raised. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

See for reference https://bugzilla.gnome.org/show_bug.cgi?id=648079 https://bugzilla.gnome.org/show_bug.cgi?id=648080 At one point I had a patch with a workaround for this WM behaviour. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=37052 --- Comment #3 from Vincent Povirk <madewokherd(a)gmail.com> --- ICCCM does say this, though: When a window makes a transition from the Normal state to either the Iconic or to the Withdrawn state, clients should be aware that the window manager may make transients for this window inaccessible. Clients should not rely on transient windows being available to the user when the transient owner window is not in the Normal state. When withdrawing a window, clients are advised to withdraw transients for the window. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

http://bugs.winehq.org/show_bug.cgi?id=37052 --- Comment #4 from Jasper St. Pierre <jstpierre(a)mecheye.net> --- Yes, the ICCCM never explicitly says that WM_TRANSIENT_FOR needs to be mapped. What it *does* say, however, is that the WM should treat unmapped windows as windows that don't exist from its point of view. So from the point of view of the WM, an unmapped window in WM_TRANSIENT_FOR is an invalid value, since it's effectively the same as a window that doesn't exist. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
