Description
I can't pinpoint when this happened, but recently the drawing of the diagram view in OMEdit seems to have changed. It looks like anti-aliasing was switched off, I get pretty ugly stairs on oblique edges, see attachment.
I had first noticed this with a 64 bit version, but now it's in a 32 bit version, too.

We never had Anti-aliasing in diagram view.
It has surely something to do with Qt version. Can you install older version (e.g 1.9.6 I guess) and and provide a screenshot?
Btw, which component it is in the screenshot? Is it from the MSL?

Most likely the switch to Qt5 is to blame. There is not difference now between the 32 and 64 bit version, only the compiler mingw32 gcc 5.3.0 vs mingw64 gcc 5.3.0 but everything else is the same. Hopefully Adeel can find the issue.

OK, I'll install an older version and will make a screenshot (probably on Monday, though).
It's a self-made component, not MSL.

I will look into it. Can you provide a sample model as well?

I'll try on Monday. I just realised, it could be that OMedit started rendering bigger linewidths correctly? I'll check my model when I'm back.

OK, repro model attached. It primarily seems to be the line thickness (default 0.25 vs. 1) that has started to be rendered, and AA was never present. I guess the sawtooth just became more noticeable/jarring with thicker lines.
I'll close this ticket, and just make my lines thin again. :D

I think I saw somewhere that you switched Qt versions recently, coudl that be connected? I am pretty sure that the model looked better/differnen before, but I don't have a screenshot to compare.
