And there I was thinking I was having no glitches... I was wrong.

 

My tablet was lying somewhere all day doing nothing for hours after I had switched it back on this morning and when I took it and pushed the on button...boom, total glitch stuff in the unlock screen. I couldn't even unlock it and after a few times trying to it totally shut down and I had to reboot the thing. After that everything was fine again.

 

So, conclusion: I guess there's a memory leak in the display driver that has to be fixed.

 

For comparison:

Read 23.78 MB/s Write 17.43 MB/s on Kasty 4.4.2

I almost forgot to mention, but I had that too! It was like the first time I booted up the tablet after flashing to this ROM. I got those (pretty severe) distortion/artifacts, but in the unlock screen only. After rebooting it was fine again and I've never seen it again so far.

This Rom is so good. However I found that it doesn't support ntfs write and it doesn't read exfat formatted microsd. I really like to have >4g file support back cause I want to watch 1080p videos on it, which are mostly > 4g. It can read ntfs, but just can't write to ntfs. It means I can't do use the microsd to do titanium backup.

 

Kasty, can you add ntfs write support or full exfat support?

Problem solved. Installed SELinux Mode Changer app, chose Permissive mode. I can now write to ntfs.

I just had some funny glitches again whil scrolling Google search results in Chrome browser.

Maybe we have to twiddle a bit with the ro.hwui settings in build.prop since these seem to control Android's 2D hardware accelerated rendering pipeline.

Can someone please post the build.prop file from a 4.2 ROM ?

How come you guy have such good read write speed, I bought mine in less than a month ( running kasty 1.20) but only get 11ish read and 7ish write, are there any difference between fresh clean system (minimal apps) and fully loaded system?

I did some tests with different I/O schedulers:

CFQ      Read 24,31 MB/s, Write 12,71 MB/s
NOOP    Read 23,69 MB/s, Write 15,21 MB/s
Deadline Read 24,73 MB/s, Write 14,92 MB/s

You can see NOOP and Deadline perform substantially better than CFQ. The difference between NOOP and Deadline however is negligible.

Anyone here notice that the display quality pf the 4.4 version not as good as the 4.2.2?

Is this related to the display driver?

I just checked iFive's forum (translated) and they are reporting the same issues on ifive X2 4.4.2 V2.0.0 firmware. Here are some of the comments (translated from chinese):

It seems that there is some problem, so painted!

Certain probability ghosting

Posted at 2014-1-10 12:16 Vulcan king
after power has been automatically double shadow, it is simply impossible to turn off and then turn on the screen, will be good for a while, and then continue to double image, reboot is useless, I decisive brush back ...
badbi3 Posted at 2014-1-11 20:46
I was ghosting, reset or so later. Wait and see there is no solution, it is impossible to brush back

Automatic boot after been double shadow, it is simply impossible to turn off the screen and then turn, will be good for a while, and then continue to double image, reboot is useless, I determined to brush back ...

This indicates the issue is present in the original ROM, so it is very likely not even possible for kasty to fix.

I just had some funny glitches again whil scrolling Google search results in Chrome browser.

Maybe we have to twiddle a bit with the ro.hwui settings in build.prop since these seem to control Android's 2D hardware accelerated rendering pipeline.

 

http://source.android.com/devices/tuning.html

 

Can someone please post the build.prop file from a 4.2 ROM ? 

Flowdesign, just an FYI.

I tried mucking around with a number of those settings and found that a number of them put my tablet into a boot loop. I then had to restore the old build.prop via adb then reboot.

Just to confirm that our modifications to the stock firmware are always very conservative and should not bring glitches such as the ones reported in this topic, these are definitely an issue from the manufacturer firmware.

 

Also, I have posted a minor custom firmware update, see post #1:

  • Edit 2014/01/14: updated SuperSU to latest version 1.89 (free version)
  • Edit 2014/01/14: added Google Experience Launcher (GEL) in addition to PiPO's stock launcher
  • Edit 2014/01/14: use optional package to fix broken apps (Contacts/People and Calendar sync)

Download: kasty-fnf_ifive_x2-442-200_20140108-rooted4c.zip

Use Rockchip Batch Tool version 1.7 to flash the firmware, use Restore button.

I've changed some ro.hwui items too but mine boots just fine.

Although it doesn't seem to make any difference at all for the screen.

I'm thinking it must be a GPU (Mali-400) driver thingy and not the screen itself, because on a FullHD TV connected over HDMI I see exactly the same gliches (for instance when scrolling text in Chrome).

You've posted a 4.2.2 build.prop twice, not 4.4.2 😉
