Just found something interesting.
In djview4 with xepdmgr, when I flipped the page, there was always a redundant screen refreshment even after the page was properly displayed. That is, to display a page, the screen refreshes two times in a second, even though the first refreshment already does pretty well.
I thought maybe I can eliminate the second refreshment by using xepdmgrclient as Antartica instructed here:
https://www.mobileread.com/forums/sho...6&postcount=47.
After I incorporated xepdmgrclient into djview4, the flckering effect did vanish, and left a side effect of slight ghosting. Without xepdmgrclient, there was no ghosting effect.
Added:
Sorry. I gave the wrong info. I did a test with modified (using xepdmgrclinet) and unmodified (using purely xepdmgr) djview4. The result is:
The flickering problem only occurred in full-screen mode. And the ghost effect only occurred in window mode.
It seems that neither xepdmgr or xepdmgrclient have anything to do with the ghost effect and flickering problem.
