SumatraPDF running under Wine exhibits UI rendering issues where the title bar
appears black and the application temporarily draws a black layer before
rendering the actual UI elements. This creates a noticeable flickering effect
during navigation and reduces overall usability.

I've been using SumatraPDF through Wine for an extended period and can
consistently reproduce this behavior across multiple Wine versions. The
application remains functional, but these rendering artifacts impact the
experience.

Steps to reproduce:

Install SumatraPDF using Wine
Launch the application
Observe the black title bar and temporary black screen artifacts that appear
during UI rendering

The issue is consistently reproducible with a standard installation, no
additional configuration required.
