Yes your absolutely right, my problem is gone with the new build.
Thank you , for taking time to look into it. I also like your earlier changes, like the new look of the UI for manipulating the brushes, much easier to use. 
This version of Pencil2D is perfect for painting background pictures, so I better get back to practicing that then 
Quick question this Mypaint Version Pre alpha its in some Github repository ?
Yes, it exists here.
please its possible to reupload the download for the builds exes files ? 
New build:
I have been experimenting with creating a specific width slider component for the brush width, specifically to render its value in actual px, rather than some arbitrary value. In the future I intend to be able to mark the slider value with either “px” or “%” but this improvement is not quite ready yet.
There are some other QoL fixes in this release though, namely you can now scale the brush width up to 2000 px. The slider will also now truncate the label if there is not enough space
What’s new
Would it be possible to update download links ? Many thanks !
New links.
Nothing new for this branch in particular but since our last mypaint release, more bug fixes and some improvements has been added to our upstream branch, so naturally those are also included here.
Bucket Options are not showing (Windows 64). If new layer is created then Bucket Options come back but not working on lower layer even if Reference is “All layers” and upper layer has closed outline.
Thank you for your patience.
Thank you very much !!!
Bucket tool work exotic now: in order to fill whole canvas is necessary to draw at least small point, then fill work. But it is not a big deal :)
