Bug 157381

Summary: VIEWING: Inconsistent display scaling behaviour when multiple, differently scaled monitors are connected
Product: LibreOffice Reporter: Floris <info>

Status: RESOLVED DUPLICATE

Description Floris 2023-09-22 12:34:22 UTC 
Environment:

OS: Fedora Linux 38 (KDE Plasma) x86_64
DE: Plasma 5.27.7
Package: libreoffice-7.5.6.2-1.fc38.src.rpm

Three monitors connected. All monitors are 1920x1080. One monitor has 125% scaling applied, the others are at 100% scaling.

Steps to reproduce:

1. Start LibreOffice Impress (presumably also affects other applications)

Expected behaviour:

UI elements become 25% larger when the application is present on the monitor with 125% DPI scaling than they are on the other two monitors.

Actual behaviour:

UI elements are the correct size on the monitor with 125% scaling, but much larger on monitors with 100% scaling, to the point where the application becomes unusable.

If the monitor with 125% scaling is connected after LibreOffice is started, the UI elements are the correct size on the monitors with 100% scaling, but become unusably small when the window is dragged to the monitor with 125% scaling.

Thank you for the report. This is already tracked in bug 141578, so marking as duplicate.
