On NanoPC T4 board(bionic desktop image), i have LXDE and openbox desktop environment installed by default.

Now i need to do some settings to make windows transparent so that their ordering doesn't hide lower windows completely
On my other boards(Fedora and Ubuntu with openbox) i use below command to do the same.
compton -b --backend xrender

But here on NanoPC T4, when i use this command i find different behaviour on LXDE and openbox
1. LXDE
Windows are made transparent but with their content as well, andl also lot of flickering.

2. Openbox
System hangs!!!

Please can someone suggest me alternative for compton on this board.
I can explain more if my question is not clear.

Thanks.
