Help me, please.! I lost some pixels when using the transform mesh, so I have to manually mask them one by one.
I use Krita 4.4.8, but same case on Krita 5.0.6
Btw i cant use Krita 5.0.6 on my system, because Krita 5.0.6 so laggy.
But when i imported some brushes, Krita 4.4.8 so laggy too!
Thank you! 
It’s not clear what’s happening in the screenshots.
Is it a red object over a blue background layer or a red and blue object?
Can you show a full screen screenshot with the layers docker and tool options docker fully visible when the mesh transform is being adjusted.
I guess it is the small gap in the red object in 2nd screenshot.
You can change the preview mode in transform tool option docker to “Fast”, it will perform like 4.4.8
It looks like you have a grid crossover which can lead to artifacts.
The missing pixels along the grid line is something that I don’t see happening with 5.0.6.
thank you for your attention
but when i create new project with Krita 5.0.6 portable, this is what happened:
Krita 5.0.6
Reactangel tool then use transform mesh and then lost some pixel with 100% or up
Transform mesh on active
Thank you so much, you save me 
I eventually figured out that you started with a rectangle.
If you do extreme curving of the mesh grid lines:
Then yes, you do get missing pixels along the mesh grid lines:
It may be that you’ve taken it to places where it was not meant to go.
@dkazakov will know the answer to this.
I think the transform mesh has created for make extreme curving?
Yes. I guess the holes happen because you grabbed and put the edge into the middle of the object. Probably some calculations errors etc.
Excusme me, I lost some pixels on Krita 4.4.8, but same case on Krita 5.0.6 Lost some pixels with Transform Mesh
and now it’s still happening on krita 5.1.1 update
Someone help me!
What should I do? I spent a lot of time fixing it manually
