Bug ID: 171045
Summary: Calc: Rendering corruption/graphical artifacts with
Skia enabled on Windows 11 25H2
Product: LibreOffice
Version: 26.2.1.2 release
Hardware: x86-64 (AMD64)
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Calc
Assignee: [email protected]
Reporter: [email protected]
Description:
PROBLEM DESCRIPTION:
When opening a spreadsheet in LibreOffice Calc 26.2, the interface shows severe
graphical corruption: yellow/golden background covering the spreadsheet area,
green diagonal lines, and visual artifacts that make the document unreadable.
STEPS TO REPRODUCE:
1. Install LibreOffice 26.2 on Windows 11 25H2
2. Open any .xlsx file in LibreOffice Calc
3. The graphical corruption appears immediately upon opening
EXPECTED BEHAVIOR:
The spreadsheet should render correctly without any visual artifacts.
ACTUAL BEHAVIOR:
The spreadsheet area shows:
- Yellow/golden background covering the content
- Green diagonal lines across the screen
- General graphical corruption making the document hard to read
WORKAROUND FOUND:
The issue is caused by the Skia rendering engine. To fix it:
1. Close LibreOffice
2. Open the file:
C:\Users\<username>\AppData\Roaming\LibreOffice\4\user\registrymodifications.xcu
3. Find the line with "UseSkia" and change the value from "true" to "false"
4. Save the file and reopen LibreOffice
After applying this workaround, the rendering corruption disappears completely.
SYSTEM INFORMATION:
- OS: Windows 11 25H2
- LibreOffice Version: 26.2
- GPU: AMD (as seen in registrymodifications.xcu: "Advanced Micro Devices,
Inc.")
- Rendering engine: Skia (activated by default)
ADDITIONAL NOTES:
The option "Forzar representación por software de Skia" (Force Skia software
rendering)
was already enabled in Tools > Options > LibreOffice > View, but the corruption
persisted until UseSkia was set to false in the configuration file.
Steps to Reproduce:
1. Install LibreOffice 26.2 on Windows 11 25H2
2. Open any .xlsx file in LibreOffice Calc
3. Observe the spreadsheet rendering immediately after opening
Actual Results:
Severe graphical corruption appears immediately: yellow/golden background
covering the spreadsheet area, green diagonal lines across the screen,
and visual artifacts making the document very hard to read.
The issue is reproducible every time.
Expected Results:
The spreadsheet should render correctly without any visual artifacts
or graphical corruption.
Reproducible: Always
User Profile Reset: No
Additional Info:
WORKAROUND: The issue is caused by the Skia rendering engine (enabled by
default).
Fix: Open
C:\Users\<username>\AppData\Roaming\LibreOffice\4\user\registrymodifications.xcu
and set UseSkia value from "true" to "false". After this change the corruption
disappears completely.
System: Windows 11 25H2
GPU: AMD (Advanced Micro Devices)
Skia was active with "Force software rendering" also enabled, but corruption
persisted until UseSkia was fully disabled.
