[Bug 59512] New: HID devices report wrong DeviceType causing GetFileType() to return FILE_TYPE_DISK
by WineHQ Bugzilla 12 Mar '26

12 Mar '26

http://bugs.winehq.org/show_bug.cgi?id=59512 Bug ID: 59512 Summary: HID devices report wrong DeviceType causing GetFileType() to return FILE_TYPE_DISK Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: hid Assignee: wine-bugs(a)list.winehq.org Reporter: Robert-Gerigk(a)online.de Distribution: --- Created attachment 80536 --> http://bugs.winehq.org/attachment.cgi?id=80536 test program HID device handles return incorrect values for GetFileType() and NtQueryVolumeInformationFile(FileFsDeviceInformation). Windows behavior (tested on Windows 11): - GetFileType() returns FILE_TYPE_UNKNOWN (0) - DeviceType = FILE_DEVICE_UNKNOWN (0x22) - Characteristics = FILE_AUTOGENERATED_DEVICE_NAME (0x80) Wine behavior (Wine 11.4): - GetFileType() returns FILE_TYPE_DISK (1) - DeviceType = 0x00000000 - Characteristics = 0x00000000 Root cause: hidclass.sys creates child PDOs with DeviceType=0 and no IRP_MJ_QUERY_VOLUME_INFORMATION handler. GetFileType() maps DeviceType 0 to its default case, returning FILE_TYPE_DISK. This breaks .NET applications that use FileStream on HID device handles (e.g. KNX automation software ETS6), because FileStream treats FILE_TYPE_DISK handles as seekable files and fails when trying to seek on a HID device. Tested with MDT KNX USB Interface (VID 16D0, PID 0491). Windows 11 output of hid_filetype_test.exe (attached to this ticket): === HID GetFileType / DeviceType Test === HID GUID: {4D1E55B2-F16F-11CF-88CB-001111000030} Device 0: \\?\hid#msft1234#5&149340ea&0&0000#{4d1e55b2-f16f-11cf-88cb-001111000030} GetFileType: FILE_TYPE_UNKNOWN (0) NtQueryVolumeInformationFile(FileFsDeviceInformation): Status: 0x00000000 DeviceType: 0x00000022 Characteristics: 0x00000080 ...

[Bug 59508] New: SWAT 4: When pressing Alt + Tab, the game loses sound

http://bugs.winehq.org/show_bug.cgi?id=59508 Bug ID: 59508 Summary: SWAT 4: When pressing Alt + Tab, the game loses sound Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs(a)list.winehq.org Reporter: daniel.penalized(a)proton.me Distribution: --- When I press Alt + Tab (I believe it's not exactly Alt + Tab, but rather the Windows/Super/Meta key. My Alt + Tab is configured as Windows + Tab), the game SWAT 4 goes completely silent, the background video of the start menu stops and the cursor duplicates (one system cursor and another from the game itself). I don't think it's related to x11 or wayland, as it happens in both. -- Do not reply to this email, post in Bugzilla using the above URL to reply.

[Bug 59514] New: Significant time()/localtime() Performance Regression in Wine 11.4
by WineHQ Bugzilla 12 Mar '26

12 Mar '26

http://bugs.winehq.org/show_bug.cgi?id=59514 Bug ID: 59514 Summary: Significant time()/localtime() Performance Regression in Wine 11.4 Product: Wine Version: 11.4 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: ucrtbase Assignee: wine-bugs(a)list.winehq.org Reporter: wszqkzqk(a)qq.com Distribution: --- Created attachment 80538 --> http://bugs.winehq.org/attachment.cgi?id=80538 Minimal reproducer: time() / localtime() performance regression in Wine 11.4 Repeated calls to `time()` and `localtime()` are significantly slower in Wine 11.4 compared to Wine 11.3. A tight loop calling these functions 10000 times shows a clear regression in per-call cost. The same program compiled and run natively on Linux is orders of magnitude faster, confirming the overhead is in Wine's translation layer. Compared with Wine 11.3, per-call cost increases from about 12.8 us to about 319 us, roughly a **25x slowdown**. ## Environment - Host OS: Arch Linux, Latest - CPU: AMD Ryzen 5800H (laptop without power) - Wine versions tested: 11.3 / 11.4 ## Minimal Reproducer Single-file C program. See in the attachment. Build as a Windows PE executable (e.g. using a Windows-native gcc under Wine): ```bash wine gcc -O2 -o time_bench.exe time_bench.c ``` Build as a native Linux executable for baseline comparison: ```bash gcc -O2 -o time_bench time_bench.c ``` Run: ```bash # Wine wine ./time_bench.exe # Native Linux baseline ./time_bench ``` ## Reproduction Steps 1. Compile `time_bench.exe` as a Windows PE executable. 2. Compile `time_bench` as a native Linux executable on the same machine. 3. Run the PE binary under Wine 11.3 — record the output. 4. Run the same PE binary under Wine 11.4 — record the output. 5. Run the native Linux binary — record the output as baseline. 6. Compare the `ns/call` values. ## Expected Result Per-call cost of `time()` and `localtime()` should be roughly the same between Wine 11.3 and Wine 11.4. ## Actual Result Wine 11.4 shows a significant increase in per-call cost. ### Wine 11.3 ```text iterations: 10000 time() : 0.128437 s (12844 ns/call) localtime() : 0.129727 s (12973 ns/call) sink=17732949360000 ``` ### Wine 11.4 ```text iterations: 10000 time() : 3.196547 s (319655 ns/call) localtime() : 3.184343 s (318434 ns/call) sink=17732948683316 ``` ### Native Linux (baseline) ```text iterations: 10000 time() : 0.000103 s (10 ns/call) localtime() : 0.058464 s (5846 ns/call) sink=17732948500000 ``` -- Do not reply to this email, post in Bugzilla using the above URL to reply.
