[Bug 45385] New: Wrong state of virtual keys after cycling windows. Usually VK_MENU, VK_SHIFT and VK_CONTROL, but every key can be affected.
https://bugs.winehq.org/show_bug.cgi?id=45385 Bug ID: 45385 Summary: Wrong state of virtual keys after cycling windows. Usually VK_MENU, VK_SHIFT and VK_CONTROL, but every key can be affected. Product: Wine Version: 3.9 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: wineserver Assignee: wine-bugs(a)winehq.org Reporter: johnfound(a)asm32.info Distribution: --- I noticed that the state of the keys sometimes sticks in pressed state. This happens when cycling windows with some shortcut key combination. For example if cycling with Alt+Tab, on pressing Alt, the program gets WM_KEYDOWN and the state of the VK_MENU becomes pressed. But after cycling windows, the program does not get WM_KEYUP because the window is not focused and VK_MENU (and the respective VK_LMENU or VK_RMENU) remain in pressed state. When cycling back to the program window, the window get focused only after releasing Alt key, so it does not get this event as well. If cycling windows with another shortcut key combination (for example Alt+Shift+Tab - for backward cycling) both VK_MENU and VK_SHIFT keys stick. In the same time, GetAsyncKeyState returns the proper state of the keys. Note1: The problem is obviously in the wineserver code, because it handles the key state tables for the different threads. Note2: The effect happens only sometimes. It seems the code for proper processing is already there, but some racing conditions have place. Note3: There is some probability that the effect is in result of my application code, but it never happens on real Windows, so I considered it a bug. Note4: I tried to workaround this problem by reading the whole table by GetAsyncKeyState and setting it then with SetKeyboardState on WM_ACTIVATE message of the main window. This workaround actually works, but is too ugly IMO. The same trick on WM_ACTIVATEAPP does not work. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

This is only a problem with games running in Wine, native Linux games do not show this behavior. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

https://bugs.winehq.org/show_bug.cgi?id=45385 --- Comment #2 from John Found <johnfound(a)asm32.info> --- I have found a workaround. At first, I am testing under XFCE. There are two options in the "Windows manager tweaks" settings applet: [ ] Activate focus stealing protection [ ] Honor ICCCM focus hint So, I have discovered that the bug manifests itself only when both settings are switched ON. Unchecking any of them makes the bug to disappear. Still it is not very clear where is the bug actually - in the code of the XFCE WM or in WINE. Any ideas about future testing/diagnostics are welcome. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
