Band Font Size error when trying to use Gambas IDE with QT5

[JumpyVB]

I get bad font size errors in Linux Mint if I start gambas3 using this command:

Code: Select all

$ env GB_GUI=gb.qt5 gambas3

Can a fellow Linux Mint user confirm if this error is present or absent on other Linux Mint installations and not just on mine?

Code: Select all

user@nuc ~ $ env GB_GUI=gb.qt5 gambas3

I am using Linux Mint 21.2 with the Cinnamon desktop and I did not get the same error as you. There was a 'libpng' warning, but I have no idea what it means. At a quick glance, Gambas seemed to work OK.

I am using Linux Mint 21.2 with the Cinnamon desktop and I did not get the same error as you.

Thank you for confirming. That means that this issue is related to my evironment. This lead me to experiment and try to find out what this error was linked to. I was able to fix it in "Qt5 Configuration Tool" under the "Fonts"-tab.

PS: I now have no errors there on the commandline. Not even the libpng error you have.
