[PATCH v5 0/1] MR7288: winegstreamer: Avoid large buffer pushes in wg_transform.
by Yuxuan Shui (＠yshui) 26 Feb '25

26 Feb '25

## Context This is a problem discovered when running "Max: The Curse of Brotherhood" under proton. This game writes 4MB a piece into `wg_transform`, which contains about 4 seconds of compressed video. `wg_transform` calls `gst_pad_push` in `transform_ProcessOutput`, which takes \~300ms (i.e. 20 frames @ 60fps) to decode this buffer of video. So the end result is the game hitches every 4 seconds while playing cut scene videos. Proton currently has a special case for this particular game, for which it breaks up the buffer into small chunks to avoid long blocks. This MR adopts that and applies it generally. One concern raised by @redmcg is: > The only issue I can think of is if there are any decoders which don't have a parser; then they might not know how to deal with an arbitrary 4096 byte buffer (the parser is generally responsible for taking arbitrary buffers and producing something the decoder can work with, for example: a full frame). So this MR only enables this strategy when there is a parser element. -- v5: winegstreamer: Avoid large buffer pushes in wg_transform. https://gitlab.winehq.org/wine/wine/-/merge_requests/7288

[PATCH v4 0/2] MR7353: winewayland: Implement SetCursorPos via pointer lock.
by Attila Fidan (＠atticf) 26 Feb '25

There is no ([not yet?](https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requ…) dedicated protocol for requesting pointer warps, but it's possible to request one with `zwp_locked_pointer_v1.set_cursor_position_hint` which may be performed when the pointer is unlocked. The idea is to quickly lock/set position/unlock. This is used by SDL (in some cases: [SDL_MOUSE_EMULATE_WARP_WITH_RELATIVE](https://wiki.libsdl.org/SDL3/SDL_HINT…) and Xwayland. The limitation is/will be that the compositor will ignore requests to warp the pointer outside of surface bounds. What I'd like to have working is the auto cursor placement feature of some applications, where they just want to call SetCursorPos towards specific UI elements inside their single window, and usually they'll be unclipped and have a visible cursor while doing this. This patch also happens to allow mouselook to work in applications which use SetCursorPos for mouselook and aren't getting covered by the heuristics that turn on Wayland relative motion (for some reason the driver thinks the cursor is visible). Seems to affect Half-Life (GoldSrc) on my system. Though force enabling relative motion with an environment variable in a custom build or somehow improving the heuristics will also fix that. A suface/pointer can only have one lock or confinement, and this implementation depends on the pointer lock. So if needed, I temporarily unlock/unconfine in order to do the warp then relock/reconfine. I modified `wayland_pointer_update_constraint` so I don't have to temporarily disable relative motion during this in case it's enabled. I think it's safe/a no-op to attempt pointer warps while using relative motion, as according to the protocol the warp will not generate a relative motion event, and while there will be a wl_pointer motion event, they're ignored while relative motion is being used. -- v4: winewayland: Implement SetCursorPos via pointer lock. winewayland: Update locked pointer position hint. https://gitlab.winehq.org/wine/wine/-/merge_requests/7353

In fact, some HTTP server will send "Expires: -1" in HTTP response header. You are right, HTTP spec is that invalid value, include "0". I add a test to test_http_connection() that would send "Expires: -1" in response header, I get the error log: ``` 0024:err:wininet:HTTP_ParseDateAsAsctime unexpected weekday L"-1" 0024:err:wininet:HTTP_ParseDate unexpected date format L"-1" ``` Maybe we should just treat "Expires: -1" as an invalid date format and ignore it. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7323#note_95990

[PATCH v4 0/1] MR7352: winewayland: Update locked pointer position hint.
by Attila Fidan (＠atticf) 26 Feb '25

26 Feb '25

If a surface is being clipped and hides the cursor, drawing its own one, winewayland constrains using a pointer lock and enables Wayland relative motion. If the application decides to stop drawing its own cursor and make the cursor visible, winewayland will disable relative motion and pointer lock, and enable pointer confinement. The user will perceive a pointer jump from the win32/application drawn cursor to where the Wayland pointer is after being unlocked and an absolute motion event is received, because they were desynchronized due to the Wayland one being locked in place. The pointer constraints protocol says this: > If the client is drawing its own cursor, it should update the position > hint to the position of its own cursor. A compositor may use this > information to warp the pointer upon unlock in order to avoid pointer > jumps. So, right before unlocking, make a request for the compositor to warp the pointer to the win32 position on pointer unlock. -- v4: winewayland: Update locked pointer position hint. https://gitlab.winehq.org/wine/wine/-/merge_requests/7352
