Merge line is marked as dashed instead of solid

[gsardiscot4u]

I'm experiencing a minor graphic glitch in the rendering of the merge line when I switch to the branch preceding the merge.
This glitch appears when I have uncommitted files in my working directory (which can also be untracked).
I use Gittyup v1.3.0 - 2023-04-20 on Windows 11 Pro.

As-is:

Expected behavior:

Step to reproduce:

1. Create a repository and make the first commit:

git init
touch file1
git add file1
git commit -m "Add file1"

2. Create a new branch named 'feature' and commit in it:

git checkout -b feature
touch file2
git add file2
git commit -m "Add file2"

3. Optionally, add some commits to the 'master' branch to highlight the issue:

git checkout master
touch.exe file3
git add file3
git commit -m "Add file3"
touch file4
git add file4 4
git commit -m "Add file4"

4. Merge the 'feature' branch into 'master' (the '--no-ff' option is mandatory if step 3 was not performed):

git merge feature --no-ff

5. Switch back to the 'feature' branch and add a file:

git checkout feature
touch file5

It's not evident to see the merge when looking at the lines.
