Description Jim Svensson 2020-12-09 18:02:47 UTC
Description:
The grid dots are very difficult to see and make use of on a 4k monitor (27" 3840x2160 res). 

Steps to Reproduce:
1. Start a new document.
2. Enable visible grid.
3. Set grid to: Resolution = (24mm,24mm), and Subdivision (12, 12) spaces.


Actual Results:
There is grid with very tiny dots, especially the small sub-division ones.

Expected Results:
A grid that is more clearly visible.


Reproducible: Always


User Profile Reset: No


OpenGL enabled: Yes

Additional Info:
Please add an option to increase size of grid dots, or change the default to account for high resolution monitors. It looks like the smaller dots are just one pixel, which is too small.

OpenCL is enabled.

I think, it is a valid request.

You should at least set the grid color to black to make the dots better visible. And it helps to make the main grid for example 0.5mm and the spaces to 5. That results is fine dotted lines, which are better visible than single points.

Unfortunately there are a lot of problems with HiDPI.

Somewhere in the code there must be some lines to draw the dots. Code to draw dots larger than one pixel is already there becase the major grid is drawn that way. If someone that undertstands the code could please just go in and change the constants. It does not get more local change than this. All of the other many changes done in each new version must be more complicated than to fix this. It is currenty the only think preventing me from fully using this program on my new monitor.

It might be in this area:

But simple changing the base values has no effect on drawn dots for me. So it is a different place or more complicated.

Now 1.5 years later, still no improvement in version 7.3 regarding this fundamental problem with Libreoffice draw.
