QUL_PLATFORM_RENDER_BATCH_HEIGHT
Description
The render batch height defines the maximum height of a dirty area that is rendered. Default value is 0 which disables the feature. When disabled the rendering area height is not limited.
Flickering may occur when partially rendered elements are visible on a display for a short period of time. To alleviate this, maximum rendering height can be decreased, which may reduce flickering when single buffering is used.
This variable is set as a Platform target property in the CMakeLists.txt file for the target platform. See the Qt Quick Ultralite Platform Porting Guide for more information.
Note: This variable is overridden if the BoardDefaults.qmlprojectconfig contains the platformRenderBatchHeight property in the MCU.Config node.
Note: QUL_PLATFORM_RENDER_BATCH_HEIGHT is propagated to Qt Quick Ultralite runtime through Qul::Platform::PlatformContext::config().
