            Bug ID: 158461
           Summary: Flicker during live resizing when using Skia/Metal
           Product: LibreOffice
           Version: unspecified
          Hardware: ARM
                OS: macOS (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: UI
          Assignee: [email protected]
          Reporter: [email protected]

When live resizing a window on macOS, there is a brief flicker after each
resize but only when using Skia/Metal.

Steps to reproduce:

1. In LibreOffice's Options dialog in the LibreOffice > View panel, enable
Skia/Metal by setting the following checkboxes, press the OK button, and
restart if prompted:
   - Check "Use Skia for all rendering"
   - Uncheck "Force Skia software rendering"

2. Open a new Writer or Calc document and and live resize the window via a
mouse dragging a window edge or corner.

With Skia/Metal, the toolbar area will flicker with every mouse drag until you
release the mouse.

This bug does not occur with Skia/Raster or Skia disabled so my guess is that
there are some missing flushes to screen when using Skia/Metal.
