Tx, I had indeed not enabled VRGB via `eselect fontconfig`; did also so via `rox-font`, but that didn't affect qt.
However, I can rotate normal, launch a qt application, then rotate left: this works. Since KDE is not running, configuring QT>=4.5 is out of my hands (qtconfig seems limited). http://www.qtsoftware.com/developer/task-tracker/index_html?method=advsearch&searchstr=subpixel&bugs=on&sugs=on&product=1&functionalarea=486&versionfound=&versionfixed=&priority=-1&status=-1&resolution=-1 http://forum.kde.org/printthread.php?tid=11298 http://labs.trolltech.com/blogs/2008/09/01/subpixel-antialiasing-on-x11/ Seba ----- Original Message ---- From: Behdad Esfahbod <[email protected]> To: Adam Goode <[email protected]> Cc: Sebastian Glita <[email protected]>; [email protected] Sent: Friday, March 6, 2009 9:18:13 PM Subject: Re: text characters scrambled with xrandr and qt-4 Adam Goode wrote: > Behdad Esfahbod wrote: >> Sebastian Glita wrote: >>> Hi, >>> >>> Maybe this is a qt-4 problem, but here it is: >>> when: >>> >>> xrandr --output LVDS --rotate left >>> >>> and launch a QT (ver. >=4) application text is scrambled: a multicoloured >>> 20% first line each character. >> Sounds like subpixel filtering using the wrong RGB order.
