Description arne anka 2023-07-31 15:05:17 UTC

SUMMARY
I am using x2go to access a remote machine. X2go causes 
/var/log/syslog
to fill up with the exact same message, several thousand lines per second:

plasmashell[<number>]: Warning: found huge icon. The icon data may be ill-encoded. (-1 x -1)

which makes it hard to scan the file and find actually important information.
I am not quite sure why this is logged at all, but it certainly should not be logged to that extend.

OBSERVED RESULT
Log fills up with that not very informative warning.

EXPECTED RESULT
Do not log more than once per second at least.
Even better, do not log at all or allow easy configuration.

The solution is to fix the log spam, not to suppress or limit it. We don't even really have a feasible way of doing that anyway.

Can you submit a new bug report describing the actual issue itself in enough detail that we can investigate it? Thanks!

For my own future reference when you do so: the error message comes from KWindowSystem.
