By default, Bugzilla does not search the list of RESOLVED bugs.
You can force it to do so by putting the upper-case word ALL in front of your search query, e.g.: ALL tdelibs
We recommend searching for bugs this way, as you may discover that your bug has already been resolved and fixed in a later release.

Description Ilya Dogolazky 2019-11-26 07:07:25 CST 
Sometimes (not 100% of all cases but quite often), memory usage of Xorg process grows all the time, it's now 57 of available 170 GB virtual memory after 1 day running and in two or three days the system will kill Xorg because of the virtual memory will end.

Here is the output of "xrestop" saying that most of the memory is used
by something called "KDE Desktop" (83288171K is about 80 GB):

xrestop - Display: localhost
Monitoring 42 clients. XErrors: 6
Pixmaps: 180143985089564 total
Other:  164K total, All: 180143985089565 total

res-base Wins  GCs Fnts Pxms Misc   Pxm mem  Other   Total   PID Identifier

.....

After a while the X-server will crash due to the exhausting of virtual memory.

I upgraded recently from version "4:14.0.5-0debian9.0.0+0" running on Debian Stretch to the version "4:14.0.7~pre0-0debian10.0.0+1" running on Debian Buster. The same behavior as before the upgrade.
