Adjusting the tracker bug list, this is not a regression from dca01def7885ad69cf66edd75cf8207a5adb64f9.

STR from dupe 122832 for Sidebar Gallery items flicker without OpenGL rendering (i.e. not double buffered).

On a Windows build
Use default GDI rendering (Tools -> Options -> View) no HA, no OpenGL
Open Writer, Calc, Draw or Impress
On Sidebar select Gallery deck, any theme (default is Arrows)
mouse pointer over several graphic thumbnails

Note lack of double buffering and the UI flicker when redrawn.

As Skia with Vulkan will replace OpenGL UI rendering on all platforms, it does not make sense to keep OpenGL UI reports open.
