Tabs contents are overlapping with each other when sliding between multiple tabs

Things I have tried
I have tired reinstalling obsidian, updating obsidian, removing css snippets and restoring default theme. They all still causes the same issue when I am trying to switch between tabs but am not using the stacked tabs.

What I am trying to do
I am trying to figure out if there is a way to stop the contents from overlapping. It looks like a tab is transparent with other tabs and makes it really difficult to see any of the contents in each file that is opened.
