Hi, I have strange issue running most recent Qt sources on Tizen emulator (qemu i586). Also I know that there are issues with supporting HW acceleration. For example I need to export QML_BAD_GUI_RENDER_LOOP=1 because multithreaded OpenGl is a little broken there.
Anyway: When I run simple Qml App (ApplicationWindow with rectangle) I get: >>>> QtHelloWorld: client_gl.c:1585: glGetBufferSubDataARB: Assertion `offset + size <= buffer->size' failed. Aborted (core dumped) after setting (noopaque is significant because it prevents app from crash) QSG_RENDERER_DEBUG=render,build,change,upload,rootfs,dump,noalpha,noopaque,noclip I get: Batch thresholds: nodes: 64 vertices: 1024 Using buffer strategy: static dirty: Added RootNode 0x9ba3a58 dirty= 0 ) dirty: Matrix TransformNode( 0x9ba3a90 identity dirty= 0 ) dirty: Added Node( 0x9bc79b0 dirty= 0 flags= 1 ) dirty: Added TransformNode( 0x9bc73e0 identity dirty= 0 ) Updater::updateStates() - nodes have been added - transforms have changed RootNode 0x9ba3a58 dirty= 0 ) TransformNode( 0x9ba3a90 identity dirty= 0 ) Node( 0x9bc79b0 dirty= 0 flags= 1 ) TransformNode( 0x9bc73e0 identity dirty= 0 ) Node( 0x9bc72d8 dirty= 0 flags= 1 ) TransformNode( 0x9bc7498 identity dirty= 0 ) Node( 0x9bc76c0 dirty= 0 flags= 1 ) TransformNode( 0x9bc76f0 identity dirty= 0 ) Node( 0x9bc7808 dirty= 0 flags= 1 ) GeometryNode( 0x9bc7838 strip #V: 4 #I: 4 x1= 0 y1= 0 x2= 100 y2= 100 materialtype= 0xb77093e4 ) dirty= 0 TransformNode( 0x9bc7550 identity dirty= 0 ) Node( 0x9bc77a8 dirty= 0 flags= 1 ) TransformNode( 0x9bc7608 translate 0 600 0 dirty= 0 ) Node( 0x9bc77d8 dirty= 0 flags= 1 ) Renderer::render() QSGRenderer(0x9bc6528) "rebuild: full" Opaque render lists (complete) : - element: 0x9bc79e0 batch: 0x0 node: GeometryNode( 0x9bc7838 strip #V: 4 #I: 4 x1= 0 y1= 0 x2= 100 y2= 100 materialtype= 0xb77093e4 ) dirty= 0 order: 1 Alpha render list: (complete) : Opaque Batches: - Batch 0 0x9bc7ff8 upload root: 0x0 - element: 0x9bc79e0 node: GeometryNode( 0x9bc7838 strip #V: 4 #I: 4 x1= 0 y1= 0 x2= 100 y2= 100 materialtype= 0xb77093e4 ) dirty= 0 1 Alpha Batches: Uploading Opaque Batches: - batch 0x9bc7ff8 first: 0x9bc79e0 root: 0x0 merged: 1 positionAttribute 0 vbo: 0 : 76 - uploading element: 0x9bc79e0 GeometryNode( 0x9bc7838 strip #V: 4 #I: 4 x1= 0 y1= 0 x2= 100 y2= 100 materialtype= 0xb77093e4 ) dirty= 0 0x9bc7e78 48 64 -- Vertex Data, count: 4 - 12 bytes/vertex --- 0: 0:(2,float * 100 0 ) 1:(4,ubyte 255 0 0 255 ) Z:(0) --- 1: 0:(2,float * 0 0 ) 1:(4,ubyte 255 0 0 255 ) Z:(0) --- 2: 0:(2,float * 100 100 ) 1:(4,ubyte 255 0 0 255 ) Z:(0) --- 3: 0:(2,float * 0 100 ) 1:(4,ubyte 255 0 0 255 ) Z:(0) -- Index Data, count: 6 --- 0 0 1 2 3 3 -- DrawSet: indexCount: 6 vertices: 0 z: 48 indices: 64 --- vertex/index buffers unmapped, batch upload completed...
