[PATCH 0/1] MR10589: vbscript: Add missing runtime error constants and tests.
by Francis De Brabandere (＠francisdb) April 7, 2026

April 7, 2026

Add VBSE_DUPLICATE_KEY (457) and VBSE_CLASS_NOT_DEFINED (506) error code definitions with their string resources, and add tests for runtime errors 11, 94, 429, 451, 457, and 506. Errors 94 and 506 are marked todo_wine as Wine currently returns incorrect error codes for those cases. Error 28 (out of stack space) is included commented out as Wine crashes with a stack overflow instead of raising the error. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10589

wined3d: fix vk swapchain rendering too dark by supporting UNORM to SRGB conversion for brightness similar to gl This merge request addresses: https://bugs.winehq.org/show_bug.cgi?id=45364 Frostpunk is very dark Very dark rendering issues for Frostpunk seem to match the same problem for Vulkan renderer for "Against the Storm": - https://bugs.winehq.org/show_bug.cgi?id=58632 - https://bugs.winehq.org/attachment.cgi?id=80656 Running both games with gl renderer seems to fix excessive darkness: - https://bugs.winehq.org/attachment.cgi?id=80654 - https://bugs.winehq.org/attachment.cgi?id=80690 Vulkan renderer seems to be missing SRGB conversion handling availiable for GL renderer.

Changing VkSwapchainCreateInfoKHR imageColorSpace from VK_COLOR_SPACE_SRGB_NONLINEAR_KHR for `wined3d_swapchain_vk_create_vulkan_swapchain()` had no effect despite enabling VK_EXT_swapchain_colorspace for dlls/win32u/vulkan.c `convert_instance_create_info():` https://docs.vulkan.org/refpages/latest/refpages/source/VkColorSpaceKHR.html Therefore converting UNORM to SRGB was chosen similar to how the GL renderer seems to handle it: ``` static const struct wined3d_format_srgb_info format_srgb_info[] = { {WINED3DFMT_R8G8B8A8_UNORM_SRGB, WINED3DFMT_R8G8B8A8_UNORM}, {WINED3DFMT_BC1_UNORM_SRGB, WINED3DFMT_BC1_UNORM}, {WINED3DFMT_BC2_UNORM_SRGB, WINED3DFMT_BC2_UNORM}, {WINED3DFMT_BC3_UNORM_SRGB, WINED3DFMT_BC3_UNORM}, {WINED3DFMT_B8G8R8A8_UNORM_SRGB, WINED3DFMT_B8G8R8A8_UNORM}, {WINED3DFMT_B8G8R8X8_UNORM_SRGB, WINED3DFMT_B8G8R8X8_UNORM}, {WINED3DFMT_BC7_UNORM_SRGB, WINED3DFMT_BC7_UNORM}, }; ``` Its unclear whether SRGB conversion should always happen or only for particular games so the patch leaves the Vulkan renderer without SRGB conversion by default. Therefore the patch adds a new WINE_D3D_CONFIG flag named "vk_swap_srgb" to force the Vulkan renderer to perform SRGB conversion for the swapchain. By default vk_swap_srgb is set to FALSE or 0: `WINE_D3D_CONFIG=vk_swap_srgb=0,renderer=vulkan` To force vk_swap_srgb to TRUE or 1: `WINE_D3D_CONFIG=vk_swap_srgb=1,renderer=vulkan` For example, launching Frostpunk via the following after the patch fixes the dark rendering for Vulkan and appears brighter similar to the GL renderer: `WINEDEBUG=-all mangohud --dlsym WINE_D3D_CONFIG=csmt=0x1,renderer=vulkan,vk_swap_srgb=1 WINEPREFIX=/home/any/wine_stianlow_wow64_new_pfx ~/tmp/wine_stianlow_wow64_new_install/bin/wine /home/any/wine_stianlow_wow64_new_pfx/drive_c/GOG\ Games/Frostpunk/Frostpunk.exe` ``` Some SRGB handling was added several years ago but not for mappnig UNORM to SRGB that this patch adds: 6f55c8d1c56 * wined3d: Use an sRGB fallback format for sRGB formats in wined3d_swapchain_vk_select_vk_format(). Author: Henri Verbeet <hverbeet(a)codeweavers.com> CommitDate: Wed Dec 9 16:29:28 2020 +0100 ``` If UNORM to SRGB should be enabled by default then this patch may be changed so that vk_swap_srgb defaults to TRUE. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10567

New stuff looks good to me, ~~but I do think you should use the constant APPLICATION_USER_MODEL_ID_MAX_LENGTH rather than a hardcoded 128.

That is correct. The corresponding `snd_rawmidi_drain()` in the Rawmidi API would work, but Wine does not use the Rawmidi API, but the Sequencer API. When using the sequencer, `snd_seq_ev_set_direct()` marks the SysEx data for immediate out of band delivery (which is indeed preferable for SysEx data) bypassing the output queue, but that also means `snd_seq_drain_output()` and `snd_seq_sync_output_queue()` are ineffective. For what it's worth, I also tried disabling the set-direct call and adding the drain and sync calls, but there was no observable change in behaviour. -- https://gitlab.winehq.org/wine/wine/-/merge_requests/10581#note_135300
