I'm seeing this also, on alpha and amd64 (both 64-bit, but the original report
here is 32-bit)
I'm also on Gentoo, with xorg-x11-6.8.2-r1 installed on both machines. One way
to repeat the problem is to try to pop up the font menu in xterm
(ctrl-right-button). X starts grinding and takes about 1 minute to recover
before the menu will show.
The other methods mentioned above (xcalc or xfontsel) also reproduce the problem
for me. The only message I get is
Warning: Missing charsets in String to FontSet conversion
I have set in the environment:
LANG=en_US.utf8
If I unset LANG prior to running xcalc, it comes up normally with no delay.
Did some ltracing when running gvim. The long delay is clearly happening in XtConvertAndStore. (Remember that this is gvim built with Athena widgets, not gtk) $ ltrace -t gvim &> gvim-times.ltrace .... 15:20:52 XtScreen(0x120243420, 105, 0x12041e960, 0x1000002af, 2) = 0x12022e830 15:20:52 XRootWindowOfScreen(0x12022e830, 105, 0x12041e960, 0x1000002af, 2) = 56 15:20:52 XtDisplay(0x120243420, 105, 0x12041e960, 0x1000002af, 2) = 0x1202299e0 15:20:52 XGetIconSizes(0x1202299e0, 56, 0x11fffe390, 0x11fffe2a0, 2) = 0 15:20:52 XpmCreatePixmapFromData(0x1202299e0, 56, 0x120200a70, 0x12020a0d0, 0x12020a0d8) = 0 15:20:52 XtConvertAndStore(0x120243420, 0x20000974abb, 0x11fffe1a0, 0x20000974ba0, 0x11fffe1b0Warning: Missing charsets in String to FontSet conversion ) = 1 ** note huge delay here (and Warning above) ** 15:22:15 XLoadQueryFont(0x1202299e0, 0x11fffe250, 320, 0x1201a544b, 0x2000063) = 0x120486210 15:22:15 XSetFont(0x1202299e0, 0x120436c60, 0x1800008, 10, 2) = 1 15:22:15 XawInitializeWidgetSet(0x11fffc060, 8192, 0x200000a197a, 0x20000000299, 4) = 0 15:22:15 XtAddConverter(0x20000974abb, 0x20000974a84, 0x200008f22f0, 0, 0) = 0x120494d20 15:22:15 XmuCreateStippledPixmap(0x12022e830, 1, 0, 1, 9) = 0x1800009 15:22:15 XtAddCallback(0x1204ad830, 0x20000974528, 0x120176fd0, 0, 1) = 1 .... I also tested with only /usr/share/fonts/misc/ in my font path (using xset fp=). This reduces the delay considerably, but it was still there, and the warning still appeared. So the problem is not due to esoteric fonts in my font path. Possibly related to #4939? Sorry about the phenomenal bug spam, guys. Adding xorg-team@ to the QA contact so bugs don't get lost in future. Moving to a more appropriate component. Is this still an issue? Currently I'm unable to reporduce this issue with xfig. Thanks |

while having a utf-8 locale switched on, loading of an x-app with bitmapfont like xcalc or xfontsel takes a long time with high cpu-load. this seems to be caused by the underlying XLC_LOCALE in en_US.UTF-8, with missing asian encodings. strace xcalc says: select(4, [3], NULL, NULL, NULL) = 1 (in [3]) read(3, "\1\3174\0\0\0\0\0\0\0\0\0\4\0\0\0@\vL\t\1\0\0\0\220y\\"..., 32) = 32 writev(3, [{"1\0\t\0\1\0\31\0", 8}, {"*-*-*-*-*-JISX0208.1983-0", 25}, {"\0\0\0", 3}], 3) = 36 read(3, 0xbfffd400, 32) = -1 EAGAIN (Resource temporarily unavailable) as asian encodings aren't really needed with european locales it would be nice if they could be ommited. didn`t tried it with instaled jisx encodings tough.
