create new files makes pinta UI huge horizontally

[pleabargain]

I created 8 news files quickly.
The UI started looking strange(I didn't have this problem before creating multiple tabs)

pinta UI extends horizotally.
tabs sizes are fixed size so UI keeps getting BIGGER :(

see gif

desired behavior
create * tabs
Tab size SHRINKS to fit window max.
