Line chart graphs worked on kquickcharts v5.85.0 and stopped on v5.86.0. My regression test gave following result. Please fix it. 00637f36bdedd2513a6264b3d1952d61c12bf312 is the first bad commit commit 00637f36bdedd2513a6264b3d1952d61c12bf312 Author: Arjen Hiemstra Date: Mon Aug 23 17:54:26 2021 +0200 Implement batching for Line chart material This allows line chart segments and the respective material to be batched, by sending per-segment data as vertex attributes rather than uniforms. Unfortunately, OpenGL 2.1/GLSL 1.10 doesn't support array vertex attributes, so instead this emulates an array by simply defining a bunch of vertex attributes and manually converting it to an output array. src/scenegraph/LineChartMaterial.cpp | 110 +++-- src/scenegraph/LineChartMaterial.h | 33 +--- src/scenegraph/LineChartNode.cpp | 6 +- src/scenegraph/LineSegmentNode.cpp | 153 +++ src/scenegraph/LineSegmentNode.h | 4 +- src/shaders/linechart.frag | 33 src/shaders/linechart.vert | 69 ++-- 7 files changed, 239 insertions(+), 169 deletions(-) -- You are receiving this mail because: You are watching all bug changes.

https://bugs.kde.org/show_bug.cgi?id=449005 --- Comment #1 from NSLW --- Created attachment 151560 --> https://bugs.kde.org/attachment.cgi?id=151560&action=edit plasma-systemmonitor-20220824-205131.kcrash The issue occurs also in plasma-systemmonitor, but only for the following sensor faces: 1) org.kde.ksysguard.linechart 2) org.kde.ksysguard.processtable 3) org.kde.ksysguard.applicationstable Sensor faces listed below work fine: 1) org.kde.ksysguard.piechart 2) org.kde.ksysguard.textonly 3) org.kde.ksysguard.horizontalbars 4) org.kde.ksysguard.facegrid 5) org.kde.ksysguard.barchart I've created a minimal test case in QML using SensorDataModel from org.kde.ksysguard.sensors and LineChart from org.kde.quickcharts trying to narrow down the issue but alas everything works without an issue. I've modified org.kde.ksysguard.linechart to display a static chart, using an example at https://api.kde.org/frameworks/kquickcharts/html/classLineChart.html but it fails in plasma-systemmonitor as well. It crashes eventually (.kcrash log attached). I'm not sure what can influence the flickering and not really know Kirigami or KQuickCharts. Could it be that they use extensions unsupported by my gpu driver like e.g. ARB_buffer_storage (my glxinfo attached)? Such bug has been solved at https://bugs.winehq.org/show_bug.cgi?id=52663 Any ideas on what could be checked? -- You are receiving this mail because: You are watching all bug changes.
