@zetof Ok merci, c'est un peu ce dont je me doutais. Je vais donc me satisfaire des scrollings légèrement saccadés car l'écart de performance entre le driver kms et fkms pour la 3D est substantiel sur les jeux PSP, Naomi et N64. En espérant qu'un jour prochain les choses s'améliorent concernant le support du 50Hz :=)

This was reported in older version of Recalbox and it is present in Recalbox 7.1.1 still.
Randoms reboots happens when game list is scrolled, exit code 139 in log file. (tested with different sd-cards, different themes...)
Any light about this issue?

@pajarorrojo @RetroVadus
I report the bug.

@Dragu On my side, I've just tested 'scaler=none' and it's really better !
Thanks too ...

What DosBox still needs to be 100% usable on Recalbox is a virtual (on-screen) keyboard.
I've searched a bit but I found no easy solution ...
