high CPU usage with idle spyder (linux)

Hello,

I experience high CPU usage with spyder even if spyder doing nothing on linux. More over I get freeze while loading "preference" for instance.

To assess the issue I written the a quick&dirty script to monitor spyder CPU usage using cgroup cgroup-cpu-time.py. I started spyder with an empty project in it's own cgroup and just waited doing nothing and monitored CPU usage and got this:

The graph above is made with:

• Spyder version: 6.1.7 (pip)
• Python version: 3.14.7 64-bit
• Qt version: 5.15.14
• PyQt5 version: 5.15.11
• Operating System: Linux-6.18.48-gentoo-dist-x86_64-13th_Gen_Intel-R-_Core-TM-_i3-1315U-with-glibc2.43

but I got high CPU usage in all my work load with various versions of spyder. Note that the graph above is accumulated cpu usage in %, for instance 200 mean 2 cpu core at 100%

Best regards
