Describe the bug / provide steps to reproduce it

From one day to another, I started seeing a black bar appear across the bottom of previous Git hunks in the editor. This is particularly problematic when viewing single-line changes, as the bar obscures how the line looked in the past compared to the current version. The issue also occurs for multiple-line hunks, but since the bar is only at the bottom, it is less severe.

Occasionally, I can make the black bar disappear by hovering my mouse over the left dock (project panel). However, it reappears as soon as I move the mouse back to the main content area. I couldn’t consistently replicate this behavior to record a video, but it happens sporadically.
