I don't know why panning fails with some drivers and it has just been ignored,
but I think it is new that the error is returned.
What happens if you comment out the two lines in systems/fbdev/fbdev.c as
indicated?
static DFBResult
primarySetRegion( CoreLayer *layer,
void *driver_data,
void *layer_data,
void *region_data,
CoreLayerRegionConfig *config,
CoreLayerRegionConfigFlags updated,
CoreSurface *surface,
CorePalette *palette,
CoreSurfaceBufferLock *lock )
{
DFBResult ret;
FBDevShared *shared = dfb_fbdev->shared;
if (updated & CLRCF_SOURCE) {
ret = dfb_fbdev_pan( config->source.x, lock->offset / lock->pitch +
config->source.y, true );
// if (ret) <======
// return ret; <======
}
if ((updated & CLRCF_PALETTE) && palette)
dfb_fbdev_set_palette( palette );
/* remember configuration */
shared->config = *config;
return DFB_OK;
}
