Created attachment 73773 [details] strace while help>about dialog is being requested As confirmed on the IRC by MST, on 4.0 when you activate Help > About it takes around 5-6 seconds for the dialog to appear. We run LibreOffice over remote display, and MST noted that it was slower when run in this manner...but still slow even with a local video card. Prior versions of LibreOffice, this dialog opened immediately. Tested with daily 4.0 build from January 27th and still broken. Attaching the strace if this is helpful.
MST indicated that Thorsten should be added.
confirming; what i wrote on IRC: "i've just looked at it a bit, just breaking in gdb randomly, mostly i get a stack where it tries to read some graphic from the X server via XGetImage called from X11SalBitmap::ImplCreateDIB... i'm using remote X via ssh which makes this slow i guess, are you also using remote X?" "hmm if i try it on the laptop locally (not remotely) it is faster but still takes 3 seconds" "i bet it's the new SVG implementation, the slowness is inside Application::LoadBrandSVG and SvgData::ensureReplacement"
just discovered the "perf" whiteboard
