I think Windows' approach has merit if we are requesting a new start time, but for resumption I don't think it does. They don't perform any of the flushing in this scenario. So if the source changes the position significantly, then all the sinks and MFTs will have stale data. I guess they just rely on the source not doing that on resumption. But the other issue is, as you say, there will now be multiple sources of truth. If we get different values from all the different streams, which one is correct? -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7833#note_101826

[PATCH v4 0/2] MR7771: win32u: Make font handle table dynamically growable.
by Brendan Shanks (＠bshanks) 24 Apr '25

24 Apr '25

This fixes "out of realized font handles" errors seen with Valve games like Half-Life 2 (which uses more than 1000 font handles). The new limit of 5000 is roughly inspired by the Windows limit, although there are differences. On Windows 11 I can call `CreateFont()` (and then `SetMapMode()`, `SelectObject()`, `SetTextAlign()` to realize the font) exactly 5000 times before it hits the handle limit. Under Wine, child fonts use handles as well, so the limit is usually hit before 5000 `CreateFont()` calls. But, there is caching so that `CreateFont()` calls with identical arguments do not count towards the limit. Ultimately the old limit of 256 was sufficient for almost all applications, and 5000 should be enough for all but the worst-behaved apps. -- v4: win32u: Raise realized font handle limit to 5000. https://gitlab.winehq.org/wine/wine/-/merge_requests/7771

[PATCH 0/2] MR7892: winewayland: Always check the role to determine whether a surface is a toplevel.
by Alexandros Frantzis (＠afrantzis) 24 Apr '25

24 Apr '25

Since the role objects in the wayland_surface struct are part of a union, we first need to check whether the surface has the right role before checking the role objects themselves. Otherwise we risk using a subsurface as a toplevel or vice-versa. The second commit introduces a helper to deduplicate the toplevel checks. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7892

I see, this is something we do differently. We are using original session Start() timestamp when restarting the clock, and Windows apparently is using whatever source reports. I think there is a value in doing the same - the idea here I'm guessing is to adjust to the source time, which could deviate both ways from the time client asked for. What we'll need to figure out is which stamp we should actually be using for the new clock position. You can have multiple sources with multiple streams, so number of events with timestamps is potentially number of streams across all sources + number of sources. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/7833#note_101791
