[PATCH v3 0/4] MR6331: win32u: Implement DPI scaled window surface.
by Rémi Bernon (＠rbernon) 23 Aug '24

23 Aug '24

Right now this should not do anything because all windows are per-monitor DPI aware. When this is changed this will automatically fall back to window surface scaling through `NtGdiStretchBlt` in win32u. This has the disadvantage that `NtGdiStretchBlt` is doing an absolutely terrible job at upscaling. This then adds a way for drivers to opt-in and do their own surface scaling before falling back to win32u. Alternatively and perhaps better, we could pull libcairo and use it to scale the surface contents with high quality filtering instead of using GDI. -- v3: win32u: Implement DPI scaled window surface. win32u: Move window_surface creation helper to dce.c. win32u: Map window rects DPI before calling into the drivers. win32u: Map window region DPI before calling into the drivers. https://gitlab.winehq.org/wine/wine/-/merge_requests/6331

[PATCH v2 0/1] MR5890: winex11.drv: Fix a possible desktop window message queue hang.
by Zhiyi Zhang (＠zhiyi) 23 Aug '24

23 Aug '24

After an X11 event handler queues messages to another thread, TRUE should be returned and eventually propagated to X11DRV_ProcessEvents(). When FALSE is always returned in xrandr14_device_change_handler(), a possible hang can happen for the desktop message queue as follows: 1. The explorer.exe calls GetMessageW() -> NtUserGetMessage() -> wait_objects() -> wait_message(). 2. In wait_message(), user_driver->pProcessEvents() gets called in the desktop window thread to handle RRNotify events and calls xrandr14_device_change_handler() -> display_mode_changed(FALSE) -> send_message(get_desktop_window(), WM_DISPLAYCHANGE, ...) -> desktop_window_proc() -> send_message_timeout() -> send_client_message() -> process_message() -> broadcast_message() -> send_message_timeout() -> send_client_message() -> process_message() -> send_inter_thread_message() -> wait_message_reply() -> a server set_queue_mask() with skip_wait being 1 -> wake_mask and changed_mask are set to 0. 3. In wait_message(), user_driver->pProcessEvents() returns FALSE from xrandr14_device_change_handler(). So wait_message() continues to call NtWaitForMultipleObjects(). 4. Now NtWaitForMultipleObjects() hangs for INFINITE timeout because wake_mask and changed_mask for the message queue are set to 0 so the thread is not woke up. The hang is sensitive to message ordering and only happens in this specific case so it's hard to reproduce with tests. I believe some of the past test timeouts on TestBots can be attributed to this bug. -- v2: winex11.drv: Fix a possible desktop window message queue hang. https://gitlab.winehq.org/wine/wine/-/merge_requests/5890
