Screen regions not recognized on (some?) multi-monitor setups

[skewty]

gnome 3.32 (ubuntu 19.04)

My arrangement is as follows:
[1920x1200 (portrait right, centered)] [2560x1600 (landscape, main)]

The extension does not recognize the top-left and bottom-left regions on my main (right) monitor.
All regions are recognized on the secondary (left) monitor.

Is it because no corners exist on the left side of my main / right monitor?

Here is metadata.json from the version I am running (from extensions.gnome.org):

I have similar issue on my 3-monitor setup, and it's also the rightmost monitor's top and bottom left regions that are not recogninzed.

[Szymon Borucki]

Well, it actually works correctly after disabling Grouping edge tiling! @skewty maybe this will solve your issue too.

[skewty]

Yeah, disabling "Group edge tiling" seems to make it work on my Gnome Shell 3.34 installation :)

Thanks!

@SimonBo Hi Simon, your rightmost monitor is in portrait mode like @skewty 's?

[Szymon Borucki]

@emasab It's landscape

[Emanuele Sabellico]

@SimonBo is your rightmost monitor the main one? Are you using Dash to Panel too?

the extension breaks tiling with mouse on the common edge of dual monitor setup. After the extension is disabled the default tiling on the screen edge works better.

@igordovgaluk take into consideration that the default active region is one pixel in size but can be increased in the settings with the "Size of active edge tiling zone" setting.

@igordovgaluk Increasing size of active edge tiling zone solved the problem for me, thank you. It seems that this isn't so much a bug rather than a default setting that needs improvement, and possibly some documentation.
