    I am using VS2015+Qt5.9.6 to compile a 64-bit desktop application. I found that compared with 32-bit, the memory occupied by Qt components has been greatly increased, such as QLabel has almost doubled. I want to ask if this is a defect of Qt or what configuration is needed.

      How did you measure the memory needed by QLabel?
      For sure you need some more as all pointers are now 64bit wide bit this will for sure not double the needed memory footbprint.
