Hi guys, This problem could raise out of a variety of issues, first of all check the software, before diving in to hardware debugging: 1. Check whether the frame buffer drivers and other software helper libraries (blitting etc) have been enabled or used properly or not? 2. Resolution is too high??? 3. customize the GRalloc routines to make use of your frame buffer or hardware accelerators. (try benchmarking your bufferer operation on the kernel using simple framebuffer operation with out android - you can use DirectFB) 4. Try reducing the resolution and observe the behavior
Hardware items check: 1. LCD Pixel clock timing, slower timings or divider values for clock can result in slower update of display 2. LCD DMA getting starved of bus access, as other peripheral including PCMCIA or USB getting more access to bus (happened for me in case of PXA with Wifi(on PCCard) and USB heavily loading the bus) I will add more points as they come in to my mind.
