Decrease in font rendering quality on external screens

Using CoreShell on an external screen connected to my MacBook, I've noticed that the quality of font rendering is variable. It's as if the fonts were no longer legible.

This applies to both native and additional fonts, whatever the mode.

Can anyone give me a solution or have any idea of the cause of the problem?

I suppose this only affects CoreShell on the external screen as the other shells (iTerminal, VSCode...) or even CoreShell on the MacBook's screen don't seem to be affected.

MacOS Sonoma & Sequoia
CoreShell 3.10.3 (O8BEF) over Setapp

Could you please try disable "Use thin strokes" and see if fix the issue:

Sorry I was off-work for a couple of days. I turned off the mentioned option and it seems to better work. I'll update this ticket in case the problem occur again.

Regards & Thanks
