Black screen when selecting objects from a sketch

Post by dcapeletti »

Hi, when I'm in sketch editing mode and try to select several lines, the screen is black. I can't see anything from what I select. I enclose an image so you can see what it looks like.

Can it be a bug or a configuration problem?

Greetings

Did you upgrade recently to Qt5.x? Then it might be a graphics card problem, we've seen here some. If that's not the case you may try with a plain vanilla config without any styles.

In previous versions I never had that problem. I have deactivated the styles and the problem continues.

I have a slightly different behavior. Buggy to, but not as bad.

Maybe you need a special feature, go into Macros_recipes and Code_snippets, Topological_data_scripting.

In Preferences -> Anti-aliasing: NONE

This solves the error/bug/problem :) for now.
