I know from own experience, that strange things can happen, when the computer is not okay. Please check your RAM and if you overclocked it, turn it down a bit.
Check your cpu-cooler, if it is still properly atached to the cpu.
Benchmark your computer, to see if strange things happen.
I found another issue. Anything inside a selection doesnāt seem to be drawn or updated properly.
How to recreate: Make a selection then switch to a drawing tool (pen, brush or pencil) by clicking on the icons or shortcuts without terminating the selection. Draw within the selection. Your drawing would not be shown until you release your pen or mouse. Try starting your drawing from outside the selection then into the selection, your stoke would not appear in the selection. Same thing happens with the eraser and the polyline tool.
I didnāt do anything fancy with my computer. No overclocking whatsoever. No issue with it either.
The Old Pencil2D works just fine.
It really is just with the alpha version of this software with my particular OS.
Hello MrStevns!
Iām not sure if I asked this before but do you know the reason why the Mypaint version of Pencil2D deforms the colors when painting with transparency paintbrushes? You can see it in this picture if you look closely, itās large blocks appearing randomly, like itās pixelating the image but with huge pixels 
@manu Hmm seems as if those were the tiles the canvas use to make image building faster 
In these cases it might be better to tag @MrStevns so he gets the notification 
Hi Manu
Iāll need to know some more about how to reproduce this as itās not an issue Iāve seen myself yet.
Itās true what Jose mentions, that the canvas is build on tiles, but that implementation comes from mypaint and weāre not doing much to that data so iām not sure what would cause such an effect if youāre not able to reproduce that in mypaint itself.
Can you provide some more details, for example:
btw. i did get the notifications, no need to tag as long as itās a reply to me ;)
Hi again, ok so now I have found out how to reproduce.

Iāve finally had some time to look properly into this issue and the steps youāve provided does seem to produce the problem consistently.
What I know so far:
I know the problem and iām fairly certain I know the causeā¦ the question is how to fix it.
Well that will be my headache, thanks for reporting it though and for the detailed steps
New release!
@manu I believe Iāve fixed the tile issue! try out this release and let me know of your findings.
Fantastic news MrStevns !
Already downloaded and tested for a brief 15 minutes an no problems anymore whatsoever. 
Now itās possible to work non destructively with as many layers as I like. I will put it to a more thorough test as soon as I get some more P2D time, hopefully in the weekend. I have a new background planned that will be perfect to test with. This saves me a lot of time because I tried to work on only one layer to minimize the effect and I repainted problem areas many, many, many times to hide the problems as they arose.
Thanks again for finding the bug !!
This is also affecting our current nightly build. Iāve made a fix for it which I hope to have in the next release.
the download links say 404 not found can you make new links im ngl i made this account specifically for this lol
Hi makingthisaccount
Thanks for letting me know that the links are dead, Iāll see if I can get it updated in the weekend.
Pencil2D - MyPaint is perfect and absolutely brilliant for FBF animation ! Many hearty thanks for this amazing work of genius !
The links are down again. :[ Could someone please reupload them again?
Only win64:
doesnt work, it says the folder isnt found
@makingthisaccount Hi. The mypaint build links are being fixed, once they are ready MrStevns will post a new message on this thread.
That said from what Iāve read on a different conversation, there is a very time consuming problem on the mac deployment side for the entire software, not just this branch, but it is directly effecting the MyPaint branch as a result.
With this in mind, we might need to wait a bit for new links.
New build is up. Weāre now up to date with master again.
