bug in selecting items in the item frame : autoselection without the intervention of the player

What I expected to happen was that, as the player, I could select myself the item I wanted to use
but for the last 3 months, the bug is that the selection is operating by itself without me choosing the item ; when I want to use a potion for instance, my computer is selecting by itself Something else (I see the movement of selection in the frame without my intervention as the player). As a result, I cannot fight or act as I want, with the item I want

In resolving the bug, I want to be able again to select myself the item I want to use.
In terms of versions of Minecraft, I actually play with versions 1.8.8 and 1.8.9, but the choose was not offered ...

Steps to Reproduce:
1. I see the item frame
2. The selection operates by itself
3. to stop this, I go either in my inventory or in the menu
4. then I can choose but the bug occurs more or less every 2 minutes, making it very difficult to play
