[e-users] Fast mouse scrolling problem

[Dennis <den...@ut...>]

The problem (scrolling too fast freezes the scrolling for a few secs) only 
exists when i have "Clicking in a window always raises it" enabled. Although, 
i can still use my keyboard to scroll, during the "freeze". My mouse also gets 
confined to the stuttering window.

Also, when click-to-raise is enabled, I get different xev events. Not sure if 
they help.


when disabled: 2 adjacent scroll-down events, 15ms apart: no probs

when enabled: 2 adjacent scroll-down events ..
..in this case, there were 9 such button5 events, all with the same timestamp 
..the next event occured 5361ms later
..but, although the entire stuttering took 5s, the window was randomly 
scrolling within that period.
