I used the command output that you shared. There was no errors when Processes tab is opened.
A screenshot (output of 2 processes is shared):

I will test the application on virtual machine. The same distribution that you use will be used.

Did you modify the source code of the application?
Is it the latest version of the application?

Hakan Dündar · Answer 11 · Mon Aug 21 2023 20:19:24 GMT+0800 (China Standard Time)

Can you write this code in line 543 in Processes.py in the following directory?
/var/lib/flatpak/app/io.github.hakandundar34coding.system-monitoring-center/current/active/files/share/system-monitoring-center/systemmonitoringcenter

Code:
print(process_data_stat_statm_status)
There are 8 spaces at the beginning of the code.

Result:

After that, can you share the output when the application is run by using terminal and Processes tab is opened?

Note: You can close the application just after (1-2 seconds) opening the Processes tab. The output may be very long. You can also direct it to a file by adding > a_file_name.txt at the end of the terminal command.

It worked on virtual machine on Ubuntu 22.04.3.

A screenshot:

I found the problem. There is a problem in the command output that you shared. Commandline information is shown in the PID area.

Can you follow these steps?

Remove the previous print() code in Processes.py file.
Write the following code in line 890 in Processes.py file (there are 4 spaces at the beginning of the code): print(cat_output)
Run the application by using the following command: flatpak run io.github.hakandundar34coding.system-monitoring-center > smc_processes_output.txt
Open Processes tab and close the application after 1 second.
Upload the output file.

smc_processes_output.txt

I understand what the problem.
There is another cat by uutils/coreutils command one in my $PATH

I have no idea why they outputs are differently. Bug may be

If it's not difficult for you, you could write a reproducer of this problem and write an issue

Hakan Dündar · Answer 17 · Mon Aug 21 2023 21:17:22 GMT+0800 (China Standard Time)

Can you use the other cat command?

Otherwise, commandline information of a process is shown in the PID area of another process.

Is there a way to call specific cat command on your system?

d-enk · Answer 18 · Mon Aug 21 2023 21:21:13 GMT+0800 (China Standard Time)

Is there a way to call specific cat command on your system?

Yes, sure

I'm sorry for taking up your time
Thank you very much
