html - Choppy scrolling in Google Chrome due to width:100% attribute -


i using different background image each page on site using html below:

<div class="bg_img"> <img src="images/bg1.jpg" alt="background" /> </div>

when using site in ie , firefox there no problem when using in chrome there choppy / lag effect when scrolling.

i realised when remove width:100% property lag stops need scale background images. 

.bg_img img{ width:100%;  <---- problem position:fixed; top:0px; left:0px; z-index:-1; }

is there around using width:100%?

i totally change approach full page background. there better solutions setting 100% cause wrong image ratio. here's way try.

.bg_img img{   background: url(bg_img.jpg) no-repeat center center fixed;    -webkit-background-size: cover;      -moz-background-size: cover;        -o-background-size: cover;           background-size: cover; }

you can read more full page backgrounds here.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
