[linux/macOS] Flickering UI on canvas

[gentlegiantJGC]

Having potentially solved the renderer loading issue in #84 there is now a flicker from the canvas being redrawn.

This may solve the issue

This thread on Nabble was opened in July 2000...

How much of it still applies to wxPython of 2020?

[gentlegiantJGC]

It may not. I hadn't noticed how old is was. I couldn't find anything else about it

[EvilSupahFly]

I found this. Think you can make use of some of it?

Another Linux user here, having the same issue on Ubuntu 20.04. The 3D view is rendered correctly, but all buttons and other overlays are flickering, making it basically impossible to use the editor. To give some idea about the used library versions:

$ python3 -m pip install amulet-map-editor

Since I am already posting here: I also had some difficulties getting everything to compile, as there were some dependencies missing that were not resolved by pip. Installing python3-dev, libgtk-3-dev, libwxbase3.0-dev, libwxgtk3.0-gtk3-dev and python-sip-dev solved the issue. Might be handy to mention those on the setup guide as well ;-)

I still get this bug. It makes Amulet very hard to use when you can’t see the toolbars.

OS: Manjaro Cinnamon
Amulet: 0.8.7

Having this on Ubuntu 18.04, Python 3.8, amulet 0.8.7

I think I have a similar issue but on macOS 10.13 High Sierra. The toolbars are only visible during the flickering that happens only when resizing the window.

Is there somebody who do not have this issue on linux?
