SpeedCrunch is Providing Slow Math Calculations

I'm having a performance issue with SpeedCrunch 0.12 in Debian 12: sudo apt install speedcrunch First of all, I love the UI of SpeedCrunch, as a calculator, but currently (for me) it is giving very slow results for even simple math problems like 1 + 1 = 2. The tool tip shows the result instantly, but when I press the enter key (to output the result) it takes about 7 seconds to output the calculation. For just doing one calculation, I can endure the wait, but this 7 second delay (when doing multiple consecutive calculations) after every calculation is unbearable. Is this only happening for me? If so, what might be causing this? If this is a bug, are there other calculators, with a similar interface, that anyone can recommend for precise mathematics (until this is fixed)?
