it seems there is no h/w acceleration enabled here. You need to figure out why > When using OpenGL: > i.

Kindly let me know your thoughts > on this to solve. Its a question better suited for qt mailing lists. There are several optimizations that can affect this but you have to know your load. > Thanks in advance. > Regards, > Ambika > -- > _______________________________________________ > yocto mailing list > yocto@yoctoproject.org > https://lists.yoctoproject.org/listinfo/yocto
