Axis selection graphical glitch

[JohnOCFII]

Some time in the last couple of months, this strange graphical glitch has shown up when starting a new sketch in a new body in Part Design.

When you first enter the screen to select a plane, everything looks as expected, with the three axes shown in a semi-transparent way. Once I clcck into the graphics area to select a plane, all three planes turn a single solid shade.

I can open an issue on GitHub, but was curious to see if others were seeing the same thing -- or if by chance this was actually intended behavior...

I have never seen this, but my version is slightly outdated. Can you please retry with a plain vanilla config?

seems like an opengl problem, something somewhat similar was happening with the navicube on a raspberry pi. Is this on apple silicon or intel? If apple silicon, are you running the native build or the x86_64 build through roseta?

Apple Silicon with the native build. The odd thing is, the problem only appears with a brand new file, when creating the first body, and it's first sketch. After that, I don't see the problem.

Re-starting after selecting the "Reset" and "Apply" buttons in preferences seems to have resolved the issue. I've changed so little in preferences, I can't imagine what it would have been.

Thank you for the suggestion!

Thank you for the suggestion!

You're welcome - and thanks for the feedback.

most likely something graphics related, antialiasing, backlight, etc.

Turns out -- it is related to anti-aliasing in the Display preferences. Setting to "Line Smoothing" causes the issue. This is still a problem with the current development release:
