objective c - UIAlertView lags, leaves dim effect, then causes the screen to flicker on iOS 6.1.3 -


i have 1 question related screen flickering in ios 6.1.3. when dismiss uialertview (when press ok button of uialertview in app) app gives dim effect , flickering starts. works same uialertview ok button pressed.

but when leave app stable time flickering automatically stops or when change orientation mode i.e. landscape portrait again landscape flickering stops.

i got solution same problem in ios6.1.2. solution not work ios6.1.3.

this happening because you're displaying uialertview background thread - that's never officially been supported, didn't start causing problems until ios 6.1.3. anyway, launch uialertview main thread (performselectoronmainthread:) , should work fine.

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...
