Bug ID: 103758
Summary: OpenGL rendering RGB reduced to only a single band in
slide transitions and thumbnail views
Product: LibreOffice
Version: 5.3.0.0.alpha1+ Master
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: graphics stack
Assignee: [email protected]
Reporter: [email protected]
Description:
When OpenGL Rendering is enabled, the OpenGL 3D transitions flash from RGB to a
single color band just in RED and animates that layer. We had a similar OpenGL
only glitch with bug 92184--but that was as blue layers.
Possibly related, the thumbnail view previews saved to Start Center are of the
same RED band of the BMP.
Happens with OpenGL rendering is enabled with the new HarfBuzz and the old
DrirectWrite only rendering. It does not happen when default GDI+ rendering is
enabled--with either text layout.
On Windows 10 Pro 64-bit (1607) en-US with

Steps to Reproduce:
1. Enable OpenGL rendering
2. open Impress to a sample slide with PNG or JPEG image
3. apply a 3D transition
4. close Impress thumbnail created and saved to Start Center
Actual Results:
1. image in slide is inverted
2. when running transition slices show in single color band
3. on closing the presentation, thumbnail view is generated using single color
band
Expected Results:
1. canvas of slide would not invert image
2. color would not shift to single band
Reproducible: Always

This looks a bit suspect...
