Problem of boxart in emulationstation

[WarC0zes]

Hello,
I have a Boxart size problem when I return to emulationstation, but when I change games in the list and come back on the game boxart come back to the right size.

My config :
Raspberry pi 3 B
Retropie : 4.5.1
Emulationstation : 2.8.4 rp ( tested with binary or source update, same problem and tested emulationstation-dev 2.9.0, same problem)
Theme: Carbon
Resolution of the boxart is 325x600 in png.

Before :

After, when I quit an emulator and I return to emulationstation :

My gamelist.xml :
