I marked the bug as fixed on the Bug Fix List as well: https://wiki.octave.org/Bug_Fix_List_-_5.0_Release#Bugs_marked_as_regressions

While I can still reproduce with Octave 4.2.2, the ticks in the checkboxes render with the correct size with Octave 4.4.1 (and dev).

Closing as fixed.

Can someone re-verify this bug with the current 5.0.1 pre-release branch?  The bug mentioned in comment #11 has now been fixed.

I can confirm this on dev as well.

This might be related to bug #49053. Adding dependency.

Issue still present in Octave 4.3.9 alpha on Windows 10

The issue remains for me in 4.2.2

This works for me, but I am running Qt5 inside a Windows XP virtual machine.

It is possible that the newest stable release, 4.2.2, being uploaded today fixes this.  It would be worth testing with someone who experiences this problem.

It is also possible that the 4.4.0 release in one month will fix this.  I suggest re-testing at this time as well.

Just updating this regression bug that it is still present in 4.2.1

Just tried Philips build with QT5 and that made no difference in this case. Must be a regression bug.

I can now CONFIRM this behavior on a WIN7 machine: The checkboxes and their tickmarks look fine with Octave 4.0.3, but with Octave 4.2.0 (w64) the tickmarks are displayed much too small. The display setting is only 125% in my case, so I would like to conclude that this is not due to any high-dpi scaling. And this is a proper regression.

Wasn't there a change in the Octave generated dialog windows? Are those now all generated by qt, and before they were in some settings generated differently?

@jsh: You could ask Philip Nienhuis to download his mxe-octave built with qt5 (see bug #43099 comment #34) and see if those work better in this respect.

Yes, 4.2final does not fix anything. Unfortunately I can't compile Windows Octave. Somehow I do believe it must be due to a regression in Octave though, since it worked before and it so far only seems to effect the radiobuttons and checkmarks (oddly enough the checkbox boxes are scaled correctly while the check marks are far too small).

Please download and update to 4.2.0 now that the release has been made. I doubt it will have fixed this, so I'm updating the release tag assuming no change.

I think I heard that Qt 5 has better support for HiDPI than Qt 4. Can you build mxe-octave yourself with the --enable-qt5 option? The official binaries are built with Qt 4, but please build and test mxe-octave with Qt 5 so the next major Octave release can be done with Qt 5 with some confidence that it will work.

I am running Windows 10 and possibly suspect the issue is due to the hidpi scaling (200% or 2x) in my case. However, the odd things is that it so far only seem to be a problem for the radiobuttons and checkmarks (checkboxes, text, and everything else seems ok). And it worked in 4.0. Here is an image showing the issue, 4.0.3 on the left and 4.2 on the right

For dpi I get 133.77 and pixels is  1368 x 912 (which is exactly 1/2 the real resolution due to hidpi scaling). The (3:2 ratio) screen diagonal is 12.3 inches 312 mm or so.

When using the official Win32 installer (Octave 4.2.0 release) under Windows XP your little test script gives me nice checkboxes of a useful size.

What Windows version are you using?

What do you get as a result of

dpi = get(0, 'screenpixelsperinch')
pixels = get(0, 'screensize')(3:4)

and what is the physical size (in millimeters) of you monitor? Do those values match to each other? (This might be related to bug #45600.)

The checkmarks in the checkboxes now only fills a tiny part of the checkbox and the radiobutton is far too small almost even to see (this was fine in 4.0.3).

fs = 10;
p = uipanel;
uicontrol('style','radiobutton','string','foo','fontsize',fs,'parent',p,'units','normalized','position',[0 0 1 0.25])
uicontrol('style','radiobutton','string','foo','fontsize',4*fs,'parent',p,'units','normalized','position',[0 0.25 1 0.25])
uicontrol('style','checkbox','string','foo','fontsize',fs,'parent',p,'units','normalized','position',[0 0.5 1 0.25])
uicontrol('style','checkbox','string','foo','fontsize',4*fs,'parent',p,'units','normalized','position',[0 0.75 1 0.25])
