Folding Background

[Spare Time Hacker]

Hi all,
Just switched to a complete new computer, with from the scratch installation.
System is Kubuntu 20.04 with C::B as listed below.

I'd like to know how to set the background of the vertical bar of the folding in the editor window. It shows a grid background (see attached screenshot) making the folding rather difficult to read. I appreciate your help.

Thanks a lot in advance!

Hm, I guess you're on a high dpi monitor. What is the dpi of your monitor?

To change the colours go to Settings -> Environment -> Colours -> Editor : Margins XXX.

Thanks for your assistance.
Yeah, you're right I'm using a highres monitor at 3840 x 2160. However, with the settings Editor : Margin chrome colour and Editor : Margin chrome highlight colour I can set what appeares grey in my screenshot but the black grids are still the same.

Are you saying that the black grid doesn't disappear if you set both margin colours to the same value?

What is the size of the monitor you use? Or the DPI or the scaling factor?
Unfortunately I have to use a low-dpi monitor at the moment, so I cannot test this.
Would it be possible to log this in the issue tracker at sf.net, so we don't forget about it?

Are you saying that the black grid doesn't disappear if you set both margin colours to the same value?

Exactly. If I set both colours to blue the grey squares turn to blue surrounded by the black grid (see new attached image). If set to different colours, it seems to become a mix of both colours.

Display Data:

• Laptop display of 15.6" on a Thinkpad P52s
• X-Server says: 192 x 193 dpi
• Global scaling set to 250%

Would it be possible to build the stc wxWidgets sample from wx-master and test it?

[Spare Time Hacker]

To be honest, I have no clue how to do that  .

1. Download wxwidgets with git
2. run git sudmodule update --init or similar
3. setup a build folder
4. run configure
5. cd sample/stc
6. run make
7. run ./stcdemo or similar.

Okay, will try. Give me some time. Will comeback to you.

Just FIY because it was the easiest thing to do.

I reset the display scaling to 100% and the folding appearance is fine. Then I tried 200% and get the same issue. However 100% scaling is not working for me it, everything is way too small to read.

Please log an issue on the sf.net ticket tracker.

[Spare Time Hacker]

Ticket done and thanks again for looking in that matter.

I don't plan to look at this at the moment. I'm waiting for a critical mass of gtk3 related issues to gather.
