Glitches on round shapes

[simonb44879216]

Hello
Every round shape i create in illustrator looks like this.
The problem just started all of a sudden.

Does anyone know what i could do to fix this?

Try View > Preview on CPU

The Control panel says you have a 5-pt round brush on the selected object. Is that lntentional?

there's no active selection in that screenshot, so we don' t know what's applied

There have been multiple questions on this problem (with similar screenshots) (like here: Default Jagginess with every AI project  )and the artefacts all disappear when CPU preview is used (as Monika suggested).

It looks like a very recent problem after a recent update.

It would be usefull to mention it here, with system and graphic card info:
