<pre style="white-space: pre-wrap; white-space: -moz-pre-wrap; white-space: -pre-wrap; white-space: -o-pre-wrap; word-wrap: break-word;">that looks wrong. size is already width and height and users (should) be already using the right one for the situation.
some code is already using mSize(font).height()
they'll be getting totally weird results after this change
I don't think it's needed</pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">So actually only height needs to be multiplied. Also in this case (after multiplying with 1.6) the difference will be slightly bigger than in units.gridSize, because units.gridSize is rounded to even number.</p></pre>

This is with Noto Sans font that has this issue (boundingRect(QString) returns too big height) = lower height fixes the issue.</p></pre>

It now returns correctly the actual height of M character. For backwards compatibility, the value is multiplied with 1.6.</p>

Basically everything in Plasma grow too much (even though the font is visually the same or even smaller than DejaVu Sans that I was using before - same font size 9 was used) - too big spacing in task manager, too big popups (application menu, system tray popups), etc ...</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">This fixes the issue. This may also fix BUG 343349</p></pre>
