Bug ID: 172048
Summary: Rendering Issues with Skia Hardware Renderer in
Combination with UNO Remoting
Product: LibreOffice
Version: 26.2.3.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Writer

C++ program to demonstrate the issue, including a screenshot
When Writer is started on Windows via cppu::bootstrap() and controlled by an
external program, rendering issues and even crashes may occur if the Skia
hardware renderer is active. These issues do not occur when Writer is started
and used interactively by a user. The observed problems include blacked-out
areas and flickering when moving the mouse over the Writer window. This
behavior has been present at least since LibreOffice 24. Attached is a minimal
C++ example (SKIARenderIssue.zip) that demonstrates the issue by starting
Writer and creating an empty document. To build the example, install
LibreOffice 26.2.3.2 and the corresponding SDK in the default location.
Additionally, install a recent version of CMake and Visual Studio. I used CMake
4.3.2 and Visual Studio 2026 18.5.2. My runtime environment was Windows 11 24H2
with NVIDIA driver version 596.3. When you run the example, the issues will
very likely occur.
