The issue is being tracked here: https://bugs.freedesktop.org/show_bug.cgi?id=92640 Right now, it would be helpful to know what pre-release version the issue landed in. Additionally, it would be helpful to know if the issue is on the server side or in libGL. 1) Install 2.7.8, make a backup copy of /opt/X11/lib/libGL.1.dylib 2) Install 2.7.7, and replace its libGL.1.dylib with your backup. 3) Does the issue reproduce using 2.7.7 with newer libGL? 4) Make a backup copy of 2.7.7's /Applications/Utilities/XQuartz.app/Contents/MacOS/X11.bin 5) Install 2.7.8, and replace its X11.bin with your backup. 6) Does the issue reproduce using 2.7.8 with the older X11.bin? --Jeremy > Is there any news about that bug or any workaround except installing Xquartz > 2.7.7 instead of 2.7.8 ? > > All the best > > Linus > > > ------ > Dr. Alain Filhol (Computer scientist) > Institut Laue-Langevin, EPN CampusCS 20156, 71 ave des Martyrs > F-38042 Grenoble cedex 9 > <[email protected]>, Office: ILL4-217 > Tel:+33 4.76.20.71.56, Fax: +33 4.76.20.76.48 > > > > > > > _______________________________________________ > Do not post admin requests to the list.
