Bug ID: 466984 Summary: Rendering errors when PRIME is enabled Classification: I don't know Product: kde Version: unspecified Platform: Archlinux OS: Linux Status: REPORTED Severity: major Priority: NOR Component: general Assignee: unassigned-b...@kde.org Reporter: serrapmcc...@gmail.com Target Milestone: --- SUMMARY *** Somewhere around 5.27 PRIME got completely broken for my configuration (see below), and started causing graphical errors when enabled. Rolling back to a build in january fixes the issues. 5.27 caused the system to hang and become completely unusable. 5.27.2 makes the system usable in this configuration, but with graphical errors. (Mostly limited to taskbar, launcher, etc). The dummy plug (or a connected display) is required to enable the iGPU for vaapi, but having 1 iGPU display and 1 dGPU display will also produce the same result. *** STEPS TO REPRODUCE 1. set DRI_PRIME in /etc/environment 2. plug a display in to iGPU and dGPU 3. OBSERVED RESULT Rendering/gfx errors, pink or garbled taskbar, launcher, etc EXPECTED RESULT No rendering errors SOFTWARE/OS VERSIONS Operating System: EndeavourOS (Arch-Based) KDE Plasma Version: 5.27.2 KDE Frameworks Version: 5.103.0 Qt Version: 5.15.8 Kernel Version: 6.2.2-zen1-1-zen (64-bit) Graphics Platform: Wayland Processors: 20 × 12th Gen Intel® Core™ i7-12700K Memory: 30.7 GiB of RAM Graphics Processor: AMD Radeon RX 5700 XT Manufacturer: ASUS ADDITIONAL INFORMATION Mesa 22.3.6 lspci | grep VGA 00:02.0 VGA compatible controller: Intel Corporation AlderLake-S GT1 (rev 0c) 03:00.0 VGA compatible controller: Advanced Micro Devices, Inc.
