Running several numerical self-programmed packages I realized already some time ago that Mathematica 10 needed between 20 and 40% more time. I did already report this of course with a simple example to Wolfram support, but have somehow not got any official response. Investigating a bit more I w...

I've upgraded my home installation of Mathematica from version 9 to 10 today on a Windows 8.1 machine, and I'm getting a weird font issue - the fonts are not anti-aliased, and look unbalanced and weird. Just look: For comparison, here what it looks on Linux with Mathematica V10 At t...

In Mathematica 10.0.0 we have built-in graphical triangle PlotMarkers. Let us look closer on them: ListLinePlot[{{Missing[]}, {{0, 0}}}, PlotTheme -> "Monochrome", ImageSize -> 20, Ticks -> False, AxesOrigin -> {0, 0}, BaseStyle -> {Magnification -> 10, Thickness -> Tiny}] ListLinePlot[{{Mi...

With Mathematica 10 for Mac, BitShiftRight works properly on lists of up to 100000 numbers, but appears to give incorrect results when threaded over lists of 100001 or more: v1 = Table[i, {i, 1, 100000}]; v2 = Table[i, {i, 1, 100001}]; s1 = BitShiftRight[v1]; s2 = BitShiftRight[v2]; s1[[1 ;; 10]...

Apparently, BarLegend in version 10 displays tick legends in scientific notation when they are smaller in magnitude than 0.01. For instance, BarLegend[{"Rainbow", {-.015, .015}}, LabelStyle -> Directive[Black, Bold, FontSize -> 12]] creates the object How can I change the tick labels to d...

If I evaluate, with a fresh kernel Names["Global`*"] I get {"rhs", "z"} I think this is not caused by any packages in $UserBaseDirectory or $BaseDirectory, because if I evaluate the same expression under V9.0.1, which has the same strings for these variables (directories), I get Names["G...

Consider: "\бвгд" // FullForm "\\бвгд" // FullForm In v.8.0.4 I get this: "\\:0431\:0432\:0433\:0434" "\\\:0431\:0432\:0433\:0434" But v.10.0.0 adds redundant backslash before the first backslashed Cyrillic symbol: "\\\:0431\:0432\:0433\:0434" "\\\\:0431\:0432\:0433\:0434" As the r...

I recently upgraded to Mathematica 10, very excited about the multiple undo function of course. However I very quickly noticed that if I specify a setting for PlotMarkers in the ErrorListPlot function, the error bars disappear. Even just setting PlotMarkers->Automatic makes the error bars disapp...

In version 10, if we plot with Sqrt in y-axis, and export to PDF, the square root disappears in the PDF file. p = Plot[x, {x, 0, 1}, Frame -> True, FrameLabel -> {"x", "\!\(\*SqrtBox[\(y\)]\)"}] Export["test.pdf", p] This does not happen in version 9.

Please try to evaluate this code in Mathematica 10. << ComputationalGeometry` g = RandomGraph[{12, 18}]; pt = GraphEmbedding[g]; convexhull = ConvexHull[pt]; Show[PlanarGraphPlot[pt, convexhull, ColorOutput -> Red], g, Graphics[{Red, PointSize@Large, Point[#]} & /@ pt]] Works perfectly fine ...

Mathematica 10 crashes in the following (simple) situation: FormulaLookup["gas"] This command will produce a long list of possible formulas. Then I type the following command below the list (and not run it) FormulaData[] When I copy one of the formulas produced by the FormulaLookup command ...

I am trying to use AbsoluteOptions in V10 but I am getting the Out with some errors as see in this picture: does anyone have same issue?

I want to discretize 3D constructive solids, supported by Mathematica 10 regions functionality. Quality of resulting meshes must be controllable, and meshes must be useful for further computation. This should be easy, but the trivial example below stuns me. (* Simple derived region in 3D with a...
