** Information type changed from Public to Public Security
** Tags added: jammy mantic
A new symptom. While I'm working with NetBeans the system very often freezes
randomly. Only reboot helps. I see next data in log:
[ 235.747] (EE) BUG: triggered 'if (glyph->refcnt == 0)'
[ 235.748] (EE) BUG: ../../../../render/glyph.c:252 in FreeGlyph()
[ 235.748] (EE)
[ 235.748] (EE)
In my case the crash happens randomly, when I'm working with NetBeans
21. I didn't any system updates. Perhaps the NetBeans made auto update.
My log lile:
[ 356.402] (EE)
[ 356.402] (EE) Backtrace:
[ 356.403] (EE) 0: /usr/lib/xorg/Xorg (OsLookupColor+0x13c) [0x5594ee295fdc]
[ 356.404]
In my case (Android Studio 2023.2.1, also based on IntelliJ, on a fully-
updated Jammy), with the editor antialiasing set to "grayscale", the
crash is 100% reproducible (same stacktrace) as soon as any file is
opened. The default setting, "subpixel", doesn't seem to cause any
issues.
