Hi Balton i have this artifacts since 2.20 on Linux PPC. are more evident if the sdl driver is used, much less on GTK but still pres= ent there too plus GTK have issue with pointer if gl is enabled (reported i= n past in bugzilla) I found it in STD when kvm is enabled on ppc32, virtio-vga gave this issue = much less . (qemu-system-PPC64 have virtio enabled), The strange thing is the std dont gave this issue on x86 emulation via tcg.= .. I hope one day we will have virtio on ppc32 too. Luigi
