Did I say video memory?
 
What I meant is that among all of those numbers, only 1366 is not a multiple of 4 or 8, I bet there is something to do with it. 1366 is chopped to 1360, seems did a mod operation, 1366 % 8 = 1360
 
Below are testing results from our user:
 
800 x 600 - good
1024 x 768 - good
1152 x 864 - good
1280 x 600/720/768/800/1024 - good
1360 x 768 - good
1366 x 768 - xp mode runs at 1360, window cutoff alignment off center, short taskbar
1400 x 1050 - good
1440 x 900 - good
1600 x 900 - good
1680 x 1050 - good

Come on, pal! A pixel is 4-byte long in video memory. Under any resolution the video memory is 4-byte aligned. That's not the point.

There is a gap if set host display to 1366x768, what I guess is that 1366 is not 4-byte aligned.
