Created attachment 145150 [details] latest crash dump plasmashell crashes on a regular base within nvidia-glcore. It happens with nvidia-gfxG05 470.86 and 470.94. I can provide about a dozen crash dumps, but they're all similar, starting with: Application: Plasma (plasmashell), signal: Segmentation fault Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0} [KCrash Handler] #6 0x00007fcff0c1f7c6 in () at /lib64/libnvidia-glcore.so.470.94 #7 0x00007fcff0c1ffb2 in () at /lib64/libnvidia-glcore.so.470.94 #8 0x00007fcffa636faf in QOpenGLFunctions::glBindBuffer(unsigned int, unsigned int) (buffer=<optimized out>, target=34962, this=0x7fcf841259b0) at /usr/include/qt5/QtGui/qopenglfunctions.h:1139 #9 QSGBatchRenderer::Renderer::unmap(QSGBatchRenderer::Buffer*, bool) (this=0x7fcf84125840, buffer=0x7fcf87021b18, isIndexBuf=<optimized out>) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde36-1.3.x86_64/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:1221 #10 0x00007fcffa638d64 in QSGBatchRenderer::Renderer::uploadBatch(QSGBatchRenderer::Batch*) (this=this@entry=0x7fcf84125840, b=b@entry=0x7fcf87021af0) at /usr/src/debug/libqt5-qtdeclarative-5.15.2+kde36-1.3.x86_64/src/quick/scenegraph/coreapi/qsgbatchrenderer.cpp:2384 This is a two monitor combined 5120x1600 x11 desktop, that will not work with the nouveau driver. Since I maintain the openSUSE blender builds, I need to keep this to have a productive setup.

> nvidia-gfxG05 470.86 and 470.94. The old EGL-based driver support is being phased out in favor of NVIDIA's new GBM support in the 495-series driver which generally works much better. Can you upgrade to that driver version (or a later one) and see if it still happens?

Hi Nate, sorry for the log delay, just a brief update: none of the higher driver levels, neither 495.* nor 510.* wanted to play with my venerable GLX 760, hence I finally swapped my card with a RTX 3060. That one plays fine, you were right. But the problem with the G05 470 drivers should be addressed some day, since not all users are able to follow my example (and shouldn't need to..). Just FYI, there's a downside for now with, what I guess any nividia drivers and current kernel releases. I'm not able to use any kernel > 5.16.4 (tested up to 5.16.9). Oh well. Anyway, thanks for your support and have a nice weekend.
