Hey @ericolito, thanks for reporting the issue! What disto/version are you using?

[Paulie420]

I have similar, but assume its a dependancy issue? Maybe something to do w/ GLib:

I'm on a stock Ubuntu 22.04 install... will post info if I find the dependancy need, and check back if any info posted here...

Hey @ericolito, thanks for reporting the issue! What disto/version are you using?

Arch Linux. I tried downgrading the "gtk-sharp-2" package as the stable version of Pablodraw for Linux only seems to work with gtk-sharp-2 2.2.12 and below, but this didn't help when it comes to the beta version.

[ryanfantus]

Interestingly I have the same problem - Ubuntu 22.04 - but if I manually build using the included instructions and run the resulting debug binary, everything works as expected.

However, if I package everything into a standalone release build (self contained, no dll or other files), I get the same failure. Not sure if this helps but hopefully it can at least diagnose what the issue is not.

[f0086]

Is there any solution for that? This issue is closed without any fix I think.
Got the same problem :(

i have isuee on debian 12
