Bug#929573: x2go server openGL errors are printed in high volume at less than a, millisecond time-scale to the log file
Package: x2goserver
Version: 4.1.0.3-4
Debian Buster
CC: submit@bugs.x2go.org
OpenGL error messages from gl_surface_qt.cpp (qtwebengine likely) are printed on 0.01 of a millisecond time scale (i.e. 10^5 messages per second) to a log file.
Currently my log file is 16 TB in size. This is a error log file from a single session, because https://bugs.x2go.org/cgi-bin/bugreport.cgi?bug=923 is resolved.
$ls -la ~/.xsession-x2go*
-rw------- 1 user users 17557623775232 May 2 23:40 .xsession-x2go-mamut-errors
-rw------- 1 user users 38176 Jun 18 2018 .xsession-x2go-mamut-errors.old
The content of the file is extremely boring:
[...]

(ad infinitum)
I was definitely running Rstudio desktop in x2go session, but don't know if it was generating these messages.
Expected behaviour: Too quickly appearing messages from the same process should not end up in the log file. systemd-journald if I am correct has such a feature.
I am not reporting it to qtwebengine or Rstudio right now. Will do if encouraged in your comments.

Piotr
