Does a firmware exist that fixes the screen flicker on off white colours?

No this is present on the stock rom provided with the tablet. It only occurs when off white colours are used. I immediately noticed it on the Adobe app "Sketchbook Pro" as the default background colour flickered like crazy. When I filled the screen with pure white it resolved. Maybe it's a hardware limitation of the screen.... i.e. dithering to achieve colour?

Can i test only with the free app ?

Edit:
Found it, yes i noticed this on grays backgrounds actually, not white, it looks like the refresh rate is on 30 hz and that`s why you see the flickering.
It can be related to the both hardware/software side.
I already forwarded some problems to Archos with the YouTube app, which buffers only maximum 1 minute, and after that it stops, you need to skip 5 seconds of the video to get it working again.
Also a problem with the Wi-Fi when the device comes up from stand by, you cannot connect to any wi fi, unless you re-enable the Wi-Fi function, and sometimes you need to restart the tablet because not even the Wi-Fi will work.
