delay brush & pixel tool in affinity designer v2 after using artboard and creating groups

Is there any way to fix this ?, When I delete the artboard everything is normal but I really need the artboard

Welcome to the Affinity Forums & thanks for your report @Spacemassi!

I can confirm this is a known issue that is logged with our development team to be resolved, I'll be sure to 'bump' this report now to bring it to their attention once again.
Unfortunately there is no workaround to this issue at this time, outside of not using Artboards / Group layers.

I hope this clears things up
