graphical issues since last update

[SirALX]

Hi Folks,

i am using lr-ppsspp on a raspberry Pi4, great project!
But since the last update (updated from source on last monday) i have graphical bugs in nearly all games, it lookes like this:

As you can see is that the graphical mess is generated from the bottomline of the screen showing the inputs in Tony Hawk 8.
The issues look the same each time, they are not random.

Has ansyone an idea what might have happened?
I only updated the core, i did not change anything in the setup/configuration.

tia and regards!
