Git commit 801772616953ab7017722489de0c342ac9c1ed75 by Arjen Hiemstra. Committed on 11/11/2022 at 18:13. Pushed by ahiemstra into branch 'master'. declarative/core: Use two opacity nodes for fading in IconItem There's no need to create a complete custom node with material and shaders if all we're doing is a linear fade between the old image and the new. Instead we can use two QSGOpacityNodes for the fading, which gives us the same effect without the need for so much custom code. Moreover, at least one of the duplicates of 432999 points to problems in fadingnode, so this hopefully reduces the changes of that occuring.

The above fix is going to be released with plasma-framework 5.101. Hopefully, that will prevent this issue from reappearing, so I'm going to close this. Please reopen if it's not fixed.

Created attachment 159190 [details] New crash information added by DrKonqi plasmashell (5.24.7) using Qt 5.15.3 - What I was doing when the application crashed: Moving System Monitor Sensor Widget from one display to another. It first displays completely corrupted nonsensical text. Then I get a notification of a plasma crash. - Unusual behavior I noticed: After moving System Monitor Sensor Widget, the text displayed is corrupted and unreadable gibberish. - Custom settings of the application: Added "System Monitor Sensor Widget" with numerous voltages, temperatures and fan speeds displayed as text. -- Backtrace (Reduced): #4 0x00007fec767b722e in QSGBatchRenderer::Renderer::renderMergedBatch(QSGBatchRenderer::Batch const*) () at /lib/x86_64-linux-gnu/libQt5Quick.so.5 #5 0x00007fec767bcb25 in QSGBatchRenderer::Renderer::renderBatches() () at /lib/x86_64-linux-gnu/libQt5Quick.so.5 #6 0x00007fec767bd352 in QSGBatchRenderer::Renderer::render() () at /lib/x86_64-linux-gnu/libQt5Quick.so.5 #7 0x00007fec767a4924 in QSGRenderer::renderScene(QSGBindable const&) () at /lib/x86_64-linux-gnu/libQt5Quick.so.5 #8 0x00007fec767a4df3 in QSGRenderer::renderScene(unsigned int) () at /lib/x86_64-linux-gnu/libQt5Quick.so.5
