Try Vulkan/Raster on X11: export SAL_USE_VCLPLUGIN=gen export SAL_SKIA=raster instdir/program/soffice Actual Results: Immediate crash happens Expected Results: No crash should happen Reproducible: Always User Profile Reset: No Additional Info: Test is done with the latest LO 26.2 dev master. $ instdir/program/soffice --version LibreOfficeDev 26.2.0.0.alpha0 f6411560817dd9e2c07564eef100dcb8f995804f This is the terminal output which also contains back trace: X-Error: BadMatch (invalid parameter attributes) Major opcode: 72 (X_PutImage) Resource ID: 0x4c00019 Serial No: 302 (302) These errors are reported asynchronously, set environment variable SAL_SYNCHRONIZE to 1 to help debugging Unspecified Application Error Fatal exception: Signal 6 Stack: #0 sal::backtrace_get(unsigned int) in instdir/program/libuno_sal.so.3 #1 (anonymous namespace)::printStack(int) at signal.cxx:? #2 (anonymous namespace)::callSystemHandler(int, siginfo_t*, void*) at signal.cxx:? #3 (anonymous namespace)::signalHandlerFunction(int, siginfo_t*, void*) at signal.cxx:? #4 __restore_rt at libc_sigaction.c:? #5 __pthread_kill_implementation at ./nptl/pthread_kill.c:44 #6 __GI_raise at ./signal/../sysdeps/posix/raise.c:27 #7 __GI_abort at ./stdlib/abort.c:81 (discriminator 21) #8 SalAbort(rtl::OUString const&, bool) at crtstuff.c:? #9 Application::Abort(rtl::OUString const&) in instdir/program/libvcllo.so #10 desktop::Desktop::Exception(ExceptionCategory) at crtstuff.c:? #11 VCLExceptionSignal_impl(void*, oslSignalInfo*) at svmain.cxx:? #12 callSignalHandler(oslSignalInfo*) at crtstuff.c:? #13 osl_raiseSignal in instdir/program/libuno_sal.so.3 #14 X11SalData::XError(_XDisplay*, XErrorEvent*) at crtstuff.c:? #15 XErrorHdl(_XDisplay*, XErrorEvent*) at saldata.cxx:? #16 _XError in /lib/x86_64-linux-gnu/libX11.so.6 #17 _XError in /lib/x86_64-linux-gnu/libX11.so.6 #18 _XError in /lib/x86_64-linux-gnu/libX11.so.6 #19 _XReply in /lib/x86_64-linux-gnu/libX11.so.6 #20 XTranslateCoordinates in /lib/x86_64-linux-gnu/libX11.so.6 #21 X11SalFrame::HandleSizeEvent(XConfigureEvent*) at crtstuff.c:? #22 X11SalFrame::Dispatch(_XEvent*) at crtstuff.c:? #23 SalX11Display::Dispatch(_XEvent*) at crtstuff.c:? #24 SalX11Display::Yield() at crtstuff.c:? #25 DisplayYield(int, void*) at saldisp.cxx:? #26 (anonymous namespace)::YieldEntry::HandleNextEvent() const at saldata.cxx:? #27 SalXLib::Yield(bool, bool) at crtstuff.c:? #28 X11SalInstance::DoYield(bool, bool) at crtstuff.c:? #29 ImplYield(bool, bool) at svapp.cxx:? #30 Application::Yield() in instdir/program/libvcllo.so #31 Application::Execute() in instdir/program/libvcllo.so #32 desktop::Desktop::Main() at crtstuff.c:? #33 ImplSVMain() in instdir/program/libvcllo.so #34 SVMain() in instdir/program/libvcllo.so #35 soffice_main in instdir/program/libsofficeapp.so #36 sal_main at main.c:? #37 main in instdir/program/soffice.bin #38 __libc_start_call_main at ./csu/../sysdeps/nptl/libc_start_call_main.h:58 #39 call_init at ./csu/../csu/libc-start.c:128 #40 _start in instdir/program/soffice.bin Crash does not happen with: Version: 25.8.0.4 (X86_64) Build ID: 48f00303701489684e67c38c28aff00cd5929e67 CPU threads: 12; OS: Linux 6.2; UI render: Skia/Raster; VCL: x11 Locale: en-US (en_US.UTF-8); UI: en-US Calc: threaded
