Text in column header is truncated (Performance calculation) (windows, dark mode)

[Nirus2000]

I could not fix this error.
The columns are wider than needed.

@Nirus2000 - can you provide some more details (maybe in a separate issue)?
My understanding is: the columns have whatever width the user has given them (by resizing it via double click). If one double-clicks on the column header (or on the line between two column headers), it should resize the column to the widest value.

The problem is, no matter how big I make this column, the font always gets cut off like this. But this happens only here in Performance -> Calculations and here also only (!) in the Dark Theme.

Dark Theme (Windows 10)

Light Theme (Windows 10)

Thanks @Nirus2000 for the detailed explanation

I appears to happen if (and only if)

• on windows
• in dark mode
• in right aligned columns

Geeeez. A first search did not bring something up on SWT

If I remove the tree CSS styling (see below, from the org.eclipse.ui.theme bundle), then the alignment is correct (but of course not styled for dark mode). To me it looks like an Eclipse bug that the alignment is corrupted if styles are applied.

Table,
Tree {
	swt-header-color: #CCC;
	swt-header-background-color: #383D3F;
}
