NVIDIA

If you are using an NVIDIA GPU, set these environment variables before launching Zenkai to avoid rendering issues with Qt 6.

Flags

VariableValuePurpose
QT_STYLE_OVERRIDEfusionForces the Fusion Qt style to avoid theme engine crashes on NVIDIA
QT_ACCESSIBILITY0Disables the Qt accessibility stack, which can cause slowdowns and crashes with the proprietary NVIDIA driver
__GLX_VENDOR_LIBRARY_NAMEnoneBypasses the NVIDIA GLX vendor library, preventing texture corruption and rendering glitches in Qt widgets

Usage

export QT_STYLE_OVERRIDE=fusion
export QT_ACCESSIBILITY=0
export __GLX_VENDOR_LIBRARY_NAME=none
zenkai

Or in one line:

env QT_STYLE_OVERRIDE=fusion QT_ACCESSIBILITY=0 __GLX_VENDOR_LIBRARY_NAME=none zenkai

These flags are safe to use on non-NVIDIA systems as well - they are ignored by Mesa and other open-source drivers.
