### Known Issues in 2021.2.19f1 * Progressive Lightmapper: \[GPU PLM\] Crash due to out of bounds access violation in PowerSampling after enabling auto mode at the end of bake on AMD GPU ([1379762](https://issuetracker.unity3d.com/issues/gpu-plm-crash-in-nvopencl64-clgetplatforminfo-after-enabling-auto-generate-checkbox-at-the-end-of-gi-bake)) ### 2021.2.19f1 Release Notes #### Features * Version Control: Added checkout option in scene prefab view. #### API Changes * 2D: Added: Added Tilemap.GetTilesBlockNonAlloc API. #### Changes * Version Control: Updated file overlay icon size to adapt to project window zoom level. * Version Control: Updated the styling of number of items in a category in Gluon incoming changes view. #### Fixes * Android: Fixed an issue where add PlayCore dependency was added to build.gradle file if it was already added to the project as an .aar file. ([1374774](https://issuetracker.unity3d.com/issues/android-core-libraries-are-not-detected-when-theyre-just-in-the-asset-folder-when-building-app-bundle)) * Build Pipeline: Fixed an issue where BuildPlayerOptions.assetBundleManifestPath to be used when building player was not allowed. ([1399616](https://issuetracker.unity3d.com/issues/buildplayeroptions-dot-assetbundlemanifestpath-can-not-be-set-by-using-buildplayerwindow-dot-registerbuildplayerhandler)) * Burst: Fixed a bug when calling profiling `CreateMarker` on iOS, Burst could fail at runtime saying it was unable to find `CreateMarker__Unmanaged`. * Burst: Fixed a issue where burst was enabled in secondary Unity processes, including the asset import worker and out-of-process profiler (see changelog entry for 1.6.0-pre.1 for more context around this). * Burst: Fixed an access violation error that could occur when reading from a static readonly variable. * Burst: Fixed an exception that could occur if you had the Burst AOT Settings menu docked in the Editor, and then did a player build. Trying to change any of the Burst AOT Settings would throw an exception (unless you closed and reopened the Burst AOT Settings). * Burst: Fixed an issue where codegen differences could occur when using a local vector variable that was being captured by reference and passed to a called function, versus when it wasn't. * Burst: Fixed an issue where if there were two generic structs overlapping at the same `FieldOffset` in an explicitly laid out struct, a codegen error would occur. * Burst: Fixed an issue where if you used `FloatMode.Fast` with `math.pow`, where the `y` argument to `math.pow` was actually sourced from an integer, illegal codegen would be generated (LLVM would try and call out to `powf` from the cstdlib). * Burst: Fixed another rare case of the file-is-locked bug where the Burst IL Post Processor could incorrectly hold a file lock on a pdb. * Burst: Fixed errors when working with paths containing special characters. * Burst: Fixed the Burst `link.xml` output to preserve C# methods we rely on, alongside the static constructors that we preserved previously. * Burst: Improved UWP linker error message to clarify which VS components need to be installed for UWP. * Burst: Made `--burst-force-sync-compilation` command-line option actually work. * Editor: Fixed a NullReference when showing UnityEvent popup and the GameObject contained a component with a missing script. ([1388739](https://issuetracker.unity3d.com/issues/unityevent-nullreference-error-is-thrown-when-selecting-a-unityevent-function-for-a-gameobject-that-has-a-missing-script)) * Graphics: Fixed a hang on repeated calls to GraphicsBuffer.CopyCount,. ([1353308](https://issuetracker.unity3d.com/issues/crash-with-graphicsbuffer-dot-copycount-on-dx11-with-intel-integrated-graphics)) * Graphics: Fixed an issue where uniforms in ray tracing hit shaders that were not set by the user would cause wrong uniform values in other hit shaders. ([1407052](https://issuetracker.unity3d.com/issues/shader-uniform-issue-for-when-used-for-raytracing-closest-hit-shaders)) * Graphics: Improved to CullScene performance; in large scenes (10000+ Renderers) this can halve the time spent in CullScene. ([1399880](https://issuetracker.unity3d.com/issues/culling-dynamic-objects-takes-significantly-longer-in-2019-dot-4-and-above-compared-to-2018-dot-4)) * IL2CPP: Fixed an issue in which using PlayerSettings.SetAdditionalIl2CppArgs was set to multiple arguments would not work. ([1379270](https://issuetracker.unity3d.com/issues/the-argument-long-plt-is-not-present-in-the-tundra-dot-log-dot-json-log-file-when-the-project-is-built)) * Linux: Fixed "Project Setttings" and other menu items being disabled after a script recompliation. ([1380015](https://issuetracker.unity3d.com/issues/linux-player-settings-and-other-options-are-locked-after-script-compilation)) * Mono: Fixed an issue where the mono executable would be run via rosetta instead of natively on apple silicon. ([1379951](https://issuetracker.unity3d.com/issues/m1-silicon-editor-intel-mono-processes-are-initialized-when-importing-a-package-into-native-silicon-editor)) * Profiler: Fixed an issue where Custom Profiler categories were not enabled as required by the Profiler window when used in one or more modules.. ([1367356](https://issuetracker.unity3d.com/issues/profilercountervalue-does-not-appear-in-the-profiler-when-using-custom-category)) * Shaders: Fixed an issue where HLSLcc was not using half precision temps when multiple half precision sample instructions targeted the same temp register. ([1383901](https://issuetracker.unity3d.com/issues/fp32-is-used-for-a-temporary-when-compiling-a-shader-for-gles-or-vulkan)) * UI Toolkit: Fixed an invisible VisualElement with UsageHints.GroupTransform set would not apply its transform to its visible descendants. ([1402057](https://issuetracker.unity3d.com/issues/uir-invisible-group-does-not-apply-its-transform-to-its-visible-descendants)) * UI Toolkit: Fixed an issue where there was a reduction of GPU performance of the UIToolkit shader. ([1361737](https://issuetracker.unity3d.com/issues/android-uitoolkit-performance-degradation-when-visualelements-are-visible-in-scene)) * URP: Fixed an intermediate texture mode SSAO compatibility issue and updated default intermediate texture mode to always. * Version Control: Fixed a toolbar icon issue that was not displaying incoming change notifications when the Plastic window was closed. * Version Control: Fixed an error when trying to invite members to proect. * Version Control: Fixed an issue where there were editor unhandled errors being hijacked by the plugin. * Version Control: Fixed Plastic X not opening from plugin menu. * Version Control: Fixed VCCache::instance != NULL error when opening a project with Plastic window opened. * Web: Fixed an issue where UnityLoader.js macOS string was not updated to match the string SystemInfo.cpp checks against. ([1375632](https://issuetracker.unity3d.com/issues/shortcuts-with-command-key-on-macos-do-not-work-with-text-input-fields-when-player-is-webgl)) * WebGL: Fixed an issue where there was guarding of "User-Agent" header in UnityWebRequest API. ([1287962](https://issuetracker.unity3d.com/issues/webgl-user-agent-header-is-not-unguarded-when-using-unitywebrequest)) * WebGL: Fixed an issue where UnityWebRequest redirectLimit for WebGL platform was not implemented. ([1352501](https://issuetracker.unity3d.com/issues/webgl-request-is-still-redirected-when-setting-unitywebrequest-dot-redirectlimit-to-zero-on-webgl)) * WebGL: Fixed an issue wherw request url after a redirect was not updated.
