Sound like biggest difference is graphics card. 2017 imac is Radeon. I'm on "Intel Iris Plus Graphics 655 1536 MB". Stack trace looks like an unhandled exception leading to a hang.

@glennw @Electromen - what are your machine specs? Catalina? Macbook 13 2018? Thanks in advance

Working on a very simply model (my first - just a kitchen) in X11 on MBP 13 2018 (16GB ram, Quad i7). I started getting lock ups when using materials and things have progressed to more random lockups opening views and panning. The most recent stack trace looks like this at the bottom: 47 qtrender::CAOpenGLWidget::paintGL() + 169 (CAInterior + 19921801) [0x10befdb89] 47 QMetaObject::activate(QObject*, int, int, void**) + 2320 (QtCore + 2219168) [0x127728ca0] 47 qtrender::LayeredCanvasGL::paintLayers(bool) + 183 (CAInterior + 19950759) [0x10bf04ca7] 47 qtrender::LayeredCanvas::paintLayersCore(bool) + 322 (CAInterior + 19941442) [0x10bf02842] 47 qtrender::CanvasLayer::doPaint(bool) + 76 (CAInterior + 19922860) [0x10befdfac] 47 qtrender::CanvasLayer::paint(qtrender::PaintTarget&) + 55 (CAInterior + 30269943) [0x10c8dc1f7] 47 QMetaObject::activate(QObject*, int, int, void**) + 2320 (QtCore + 2219168) [0x127728ca0] 47 CanvasPaintGLController::paintGL(qtrender::PaintTarget&) + 164 (CAInterior + 7998116) [0x10b39eaa4] 47 CanvasPaintGLController::paintScene(qtrender::PaintTarget&) + 727 (CAInterior + 7998983) [0x10b39ee07] 47 qtrender::PaintTarget::Painter::~Painter() + 31 (CAInterior + 19973631) [0x10bf0a5ff] 47 qtrender::FramebufferPaintTarget::endPaintImpl() + 121 (CAInterior + 19929321) [0x10beff8e9] 47 render_engine::RenderableMesh::drawImpl(render_engine::GpuResourceContext&, unsigned long) const + 1154 (libCARender.dylib + 1362338) [0x11f50e9a2] 47 glDrawArrays_GL3Exec + 254 (GLEngine + 696989) [0x7fff3eff729d] 47 glrIntelRenderVertexArray + 254 (AppleIntelKBLGraphicsGLDriver + 58310) [0x7fff2c5323c6] 47 GenContext::ProgramPipeline() + 16522 (AppleIntelKBLGraphicsGLDriver + 76968) [0x7fff2c536ca8] 47 void updateBindingTable<SGfx3dStateBindingTablePointers>(GenContext*, unsigned int, SGfx3dStateBindingTablePointers&) + 2647 (AppleIntelKBLGraphicsGLDriver + 89325) [0x7fff2c539ced] 43 IOAccelContextAddResource + 8 (IOAccelerator + 9304) [0x7fff58820458] *38 hndl_alltraps + 223 (kernel + 928079) [0xffffff80002e294f] *29 user_trap + 684 (kernel + 2512220) [0xffffff800046555c] *29 exception_triage_thread + 417 (kernel + 1300561) [0xffffff800033d851] *24 exception_deliver + 1295 (kernel + 1299935) [0xffffff800033d5df] *23 mach_exception_raise + 269 (kernel + 1692381) [0xffffff800039d2dd] *16 mach_msg_rpc_from_kernel_body + 268 (kernel + 1320764) [0xffffff800034273c] *16 ipc_kmsg_send + 309 (kernel + 1148453) [0xffffff8000318625] *13 ipc_kobject_server + 568 (kernel + 1317272) [0xffffff8000341998] *13 ???
