Running QZXing example app against Qt5.14.1 gives OOM

I've build the QXZing example app https://github.com/ftylitak/qzxing/tree/master/examples/QZXingLive aginst 5.12.4 and 5.12.7 and it ran fine

Next I tried to build it against 5.14.1 but it resulted in continously lines like

W Adreno-ES20: <core_glDrawArraysInstancedXXX:929>: GL_OUT_OF_MEMORY

W GLConsumer: [SurfaceTexture-0-18145-0] bindTextureImage: clearing GL error: 0x505

W Adreno-ES20: <core_glDrawArraysInstancedXXX:929>: GL_OUT_OF_MEMORY

W GLConsumer: [SurfaceTexture-0-18145-0] bindTextureImage: clearing GL error: 0x505

FYI, In order to build it for 5.14.1, I had to make the following changes

• increase the minimum required SDK to 21 9in AnroidManifest.xml)
• change the NDK from r19c to r21.0.6 (I got a compiler error on including type_traits)
• the resulting binary crashed: I had to regenerate the Android Templates ("Create templates" button in Projects/build/Build android apk) because there are changes related to loading libs in the AndroidManifest.xml;
  • afterwards, I've adjusted the package name again to org.ftylitak.qzxing
• finally I had a problem with "import android.support.v4" in Utilities.java (probably due to the higher gradle version?).
  • I took a shortcut here and removed everything in Utilities.checkAndRequestPermissionList (except the last line);
  • This worked for me since I already had the permissions from the previous 5.12.7 run
