I have launch several kcalc
SUMMARY
I believe I have encountered a bug with KCalc and would like to report it. I've
observed unusual behavior,
When my system is idle, the average load is 0.42 (t=60sec), indicating that my
system is consuming 42% of the resources of a CPU core.
However, when I launch KCalc, the CPU load spikes dramatically, as if the
application is stuck in a loop calculating. Interestingly, if I move the
calculator window, everything returns to normal.
Performing a simple calculation, such as multiplying 6 by 7, does not cause any
CPU overload, but launching multiple instances of KCalc can saturate my system.
Music playback continues without issues, but capturing screenshots and closing
the offending applications becomes challenging.
I attempted to resolve the issue with the following steps, but they were
unsuccessful:
sudo apt-get remove --purge kcalc
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install kcalc
I am using KCalc version 4:22.12.3-1 on an amd64 system.
STEPS TO REPRODUCE
Launch kcalc
OBSERVED RESULT
The CPU load increases and persists even though no computations are being
performed.
EXPECTED RESULT
No CPU load
