Bug ID: 480440
Summary: [Windows] Krita should use OpenGL as the default
renderer for AMD GPUs
Classification: Applications
Product: krita
Version: nightly build (please specify the git hash!)
Platform: Microsoft Windows
OS: Microsoft Windows
Status: REPORTED
Severity: normal
Priority: NOR
Component: OpenGL Canvas
Assignee: krita-bugs-n...@kde.org
Reporter: tysont...@gmail.com
Target Milestone: ---
Currently under Windows, Krita's default "Auto" setting for renderer is using
Direct 3D 11 via ANGLE. However, AMD GPUs performs poorly under ANGLE.
Everything on the canvas appears to have a slow frame rate. Brush strokes have
visible stuttering. It's nearly unusable.
Change the renderer to OpenGL, then everything works smoothly. Maybe we should
default to OpenGL for AMD GPUs instead.
Tested under Windows 11 (23H2), with AMD Radeon RX7600 or AMD Radeon 780M
(Ryzen 7840U). The system is freshly installed, with everything up-to-date
including the latest driver (Adrenalin 24.1.1).
The performance is the same for Krita 5.2.2 and
krita-nightly-x64-5.3.0-prealpha-9a64eec01e (2024-01-28).
