After upgrading KDE to 4.6 and QT to 4.7.1, something bad happened with how Terminus font is rendered on Konsole. Attached image shows an "animation" of what happenes when cursor is moved over a text - highlited character moves to the left and whole line of text moves with it. Same thing happens with font "-schumacher-clean-*" Software: KDE 4.6 QT 4.7.1 xorg-server 1.9.2 x11-libs/libXfont 1.4.3 media-fonts/terminus-font 4.32 (tested with 4.30 too - same thing)
Created attachment 261326 [details] "Animation" showing the problem
Few additional facts: * It seems that this problem can be observed in Konsole only. KWrite works fine. * It doesn't matter what the text size is. Anything between 9 and 16 points (including fractions) gives the same result. * all tested on nvidia proprietary drivers
Just found a workaround: set DPI in system settings (KDE) to 96, and it appears that following Terminus font sizes work well now: 9, 10.5, 12, 15, 16.5. Other sizes produce the same effect as before.
I can reproduce this bug with kde-*/*-4.6.0 x11-libs/qt-*-4.7.1 x11-base/xorg-server-1.9.4 x11-libs/libXfont-1.4.3 and the proprietary nvidia-drivers-260.19.29. The spacing between the cursor and neighboring glyphs and the position of the hilighted glyph in the cursor are wrong. An additional effect seems to be very slow font rendering compared to prior qt/kde-versions.
I saw that "additional effect" too. But after setting font size to one that renders well, everything started to work fast again. Hint: On another machine I had to set "Force fonts DPI" to 96 to be able to choose a font size that renders well. Those two machines had different GPUs, drivers used: * x11-drivers/xf86-video-intel-2.14.0 * x11-drivers/nvidia-drivers-260.19.29
This issue is fixed for me with the latest update to x11-libs/qt*-4.7.2
(In reply to comment #6) > This issue is fixed for me with the latest update to x11-libs/qt*-4.7.2 Ok, resolving then. Please reopen if you disagree.
