Number and symbol boxes look funny. Angled connections are not rendered. Creating and editing patches are impossible due to lack of visual feedback.

versions:
Ubuntu 16.04
pd vanilla: 0.46.7
tcl, tk: 8.6

I suspected tcl/tk 8.6 being the culprit. I couldn't replace them with 8.5 as one of the dependencies of puredata-gui installs 8.6. Besides, I have another system with the same versions as this one but works without this issue.

Has anyone experienced the same issue? Any idea how to fix it?

@ananthp Do you get any messages in the Pd terminal about fonts?

No

@ananthp Different X window system from the other working computer?
With the same versions of Pd and Tcl/Tk it has to be something different with the os or hardware, and especially the window drawing system or the graphics drivers...... I think.
David.

@whale-av you are absolutely right. I have two machines with same os, pd, libs versions but different hardware. On the problematic machine I installed pd in a ubuntu 17.10 virtual machine and pd patches look correct. Should be a bug in the video driver version included with Ubuntu 16.04 LTS.

Thanks,
