Created attachment 1778565 [details] xscreensaver log received with "xscreensaver -v -log log.txt" Description of problem: Version-Release number of selected component (if applicable): 6.00-1.fc34 How reproducible: Steps to Reproduce: 1. Install xorg-x11-fonts-cyrillic 2. Start xscreensaver-demo application 3. Open Font Glide settings 4. Open advanced parameters and enter this command line: fontglide -root -font '*--0-*-koi8*' 5. Press OK Actual results: I see the message: No Preview Available. By clicking "Preview" I get the message on the full screen: "fontglide" crashed with status 1 Expected results: Font Glide starts. Additional info: This fontglide command line worked well in Fedora 33. I got this problem right after upgrade to Fedora 34. With default setup it does not crash, but in this case it can select fonts with which Cyrillic letters are not displayed properly.
The execution of a previous xscreensaver version was accidentally included to the log file. Ignore the part related to the version 5.44. I also have installed these fonts: fonts-KOI8-R fonts-KOI8-R-100dpi fonts-KOI8-R-75dpi It seems they should be included to the first step to reproduce too.
Sorry, the information about KOI8-R packages is wrong - they are not installed in my system.

xscreensaver 6 changed fonts handling a lot. xscreensaver 6 now uses Xft (X freetype) internally as much as possible. fontglide also changed internal a lot for font handling, now uses Xft by default. "-font" argument is still using core font, but because of this, "-font" usage is sort-of-deprecated and now no longer searches core font by "XListFonts", but checks the exact pattern given by "-font" argument. i.e. for example the following works: $ PATH=/usr/libexec/xscreensaver:$PATH /usr/libexec/xscreensaver/fontglide -font '-*-*-*-o-*-*-*-400-*-*-*-*-koi8-*' ... but (as far as I am correct) actualy the above no longer uses "multiple" fonts. and $ fontglide --font '*--0-*-koi8*' no longer works. You may ask the upstream to restore xscreensaver 5 fontglide behavior for "-font" option, however as explained above, now I guess -font option is a-sort-of-deprecated, for downstream bug I close this as WONTFIX.
