\"\"<\/p>\n

Darktable, the popular photography workflow and raw developer software, released new 5.6.2 version today.<\/p>\n

The new version is a maintenance release that mainly includes bug fixes covering OpenCL support, crashes, and memory leaks.<\/p>\n

<\/p>\n

For Intel GPUs with the most recent Compute Runtime 26.35.39758.10, the OpenCL GPU acceleration did not work<\/b> for RAW\/image processing.<\/p>\n

It’s because the new Intel driver renamed the OpenCL platform name to “Intel(R) OpenCL Graphics (integrated)<\/i>” \/ “Intel(R) OpenCL Graphics (discrete)<\/i>“. And, the previous Darktable versions did not know the new names so disabled OpenCL on initialization.<\/p>\n

\"\"<\/a><\/p>\n

Darktable 5.6.2 fixed the issue, so user can enable hardware accelerated processing with Intel GPU along with the most recent driver features.<\/p>\n

Also for OpenCL GPU acceleration, the release fixed the issue that it could incorrectly detect whether Filmic RGB contained clipped pixels on some GPUs, especially AMD GPUs.<\/p>\n

It as well fixed incorrect input gamma correction and incorrect Highlights and Laplacian processing issues when using OpenCL.<\/p>\n

For Windows, Darktable does no longer create console window Windows 11 24H2<\/b> and later. On earlier Windows versions, it fixed that the console windows repeatedly appeared when darktable or a Lua script ran an external command.<\/p>\n

It also fixed the app stealing focus and Alt+Tab failing to switch away when the mouse pointer was over a lighttable thumbnail.<\/p>\n

Others are mostly stability and crash fixes, including crashes when importing a style whose module order is empty, when an AI model returns more data than darktable reserved for it, and, when checking a faulty custom ONNX Runtime library on Windows.<\/p>\n

They also include memory leaks when expanding variables and pasting history stacks onto images in darkroom, which could accumulate with repeated image imports or exports.<\/p>\n
