[Bug: 21.4.13] Fontifying makes no progress until window focus is lost

================================================================ Dear Bug Team! When opening a perl, sh or html file and choosing Options->Syntax Highlighting->In This Buffer, the fontifying progress bar would appear and flash as if being refreshed many times a second. But no progress would actually be made. If I bring another window to the front such that Xemacs loses focus, the fontifying immediately finishes. I searched the net for similar bugs and found one: http://list-archive.xemacs.org/xemacs-beta/200305/msg00467.html As described in the above URL, editing my src/EmacsFrame.c file to undo the 2nd hunk (reverting from 1.17.2.2 to 1.17.2.1) fixed this problem (fontifying is now immediately completed). Patch to fix this problem (I'm not a programmer, so I apologize if this is not in a preferred format): *** src/EmacsFrame.c.orig Mon Jul 21 12:21:13 2003 --- src/EmacsFrame.c Mon Jul 21 12:23:15 2003 *************** *** 235,241 **** /* resource_count */ XtNumber (resources), /* xrm_class */ NULLQUARK, /* compress_motion */ TRUE, ! /* compress_exposure */ XtExposeCompressMaximal | XtExposeNoRegion, /* compress_enterleave */ TRUE, /* visible_interest */ FALSE, /* destroy */ NULL, --- 235,241 ---- /* resource_count */ XtNumber (resources), /* xrm_class */ NULLQUARK, /* compress_motion */ TRUE, ! /* compress_exposure */ TRUE, /* compress_enterleave */ TRUE, /* visible_interest */ FALSE, /* destroy */ NULL, ================================================================ System Info to help track down your bug: --------------------------------------- uname -a: SunOS sonic 5.8 Generic_108528-18 sun4u sparc SUNW,Sun-Blade-1000 ./configure '--prefix=/usr/local' XEmacs 21.4.13 "Rational FORTRAN" configured for `sparc-sun-solaris2.8'.
