This firmware has a new LeanAndMean feature setting enabled by default, which provides some faster code or shortcuts for certain screen refresh, networking, and touch gesture functions.
But unfortunately the LeanAndMean screen refresh code causes ghosting problems on the older Pearl devices, noticable when using the menus, panning, and highlighting.
The LeanAndMean feature can be disabled by adding
LeanAndMean=false to the
[FeatureSettings] section of the configuration file, which fixes most of the ghosting problems. However this also disables the LeanAndMean touch gestures.
So for those who have disabled LeanAndMean for ghosting reasons, this patch attempts re-enable just the LeanAndMean touch gestures. (Paste into libnickel.so.1.0.0.patch):
Code:
<Patch>
patch_name = `Re-enable LeanAndMean touch gestures`
patch_enable = `yes`
replace_bytes = 6ADBA4, 7C F5 E8 EF, 01 20 01 20
</Patch>
It is hard to say if this makes much of a difference, but then I didn't notice any problems with the touchscreen response before LeanAndMean, so maybe others will feel the effects more.
