When editing a drawing, if click on a Symbol Shape such as a square and then try to copy it, there's a very short period where the mouse is frozen. After pasting, there's an even longer period (maybe 0.5s) where the mouse freezes and I can't go to click on the pasted shape and move it. I've found it's not a consistent frozen period. Sometimes it's not noticeable. Also, it seems to be worse when copying multiple objects. This is mostly an annoyance, not an error.
I just noticed this delay also occurs when you hit undo or redo and it either has to delete or restore a shape.
Failed to reproduce on LibreOffice 3.4 340m1(Build:103) for OpenSuse Linux. What do you mean by "symbol shapes"? Is it the shapes inserted from the draw toolbar or symbols in special characters? I have tried both and they do not cause any delay problems. This might seem like a trivial questions but adding some steps to reproduce would be great.
I'm talking about the Symbol Shapes from the Drawing toolbar. That's the name of them when I hover over the icon. 1) Draw a Symbol Shape from the Drawing toolbar. 2) Click on the shape. 3) Hit Ctrl+C to copy. 4) Hit Ctrl+V to paste and move the mouse while doing so or shortly after. In step four, I notice a delay between pasting and getting response from the mouse. Also, moving the mouse during step 3 can cause some delay but I only noticed that after testing because I don't typically move the mouse while copying.
It seems that this is happening in some other programs, so it's not a LibreOffice bug.
This seems to be a problem I'm having across several programs. It's not just an issue with LibreOffice Calc.
