I'm using a RAIO8835, this controller can replace the SED1335 and S1D13305.
My screen is a WINSTAR320*240, white and blue.

All works correctly but i notes parasites, like the character underscore, appears on the screen, they are very very fast.
These characters are visible only on the white part of the screen, but it is due that the parasite is blue.

I have found this on a website:

I'm using a library graphic from EASYGUI and the support said to me:

"
Blinking underscores: That description sounds exactly like you disregard
the busy signal from the display controller. Some older monochrome
display controllers have a busy bit, which must be adhered to, when
accessing display RAM. The T6963 is an example of a display controller
having a busy bit. As an example see the WAIT macro in the T6963 driver
(in GuiDisplay.c). Disregarding this busy status results in your display
controller RAM write operations clashing with the internal read
operations, producing visible interference patterns on the display.
Typically only when updating is being performed. All new display
controller constructions have dual side RAM, where writing and reading
can be accomplished simultaneously."

I have tried to had a tempo but their's no result.

Have you an idea , and eventually a solution?
