Wayland Support

[00-kat]

TL;DR runs on Xwayland, is it possible to get it working on Wayland?

Is your feature request related to a problem? Please describe.

Currently, F3D runs under Xwayland. This means it can't fractionally scale. Note the text:


Also, since it can't fractionally scale, my cursor appears to be 1.5x larger than it should.
In F3D:

Everywhere else:

This is simply an X11 problem.

Describe the solution you'd like

Figure out how to use Wayland with whatever graphics library is being used (not sure if this is a Vtk problem).

Describe alternatives you've considered

• Not do anything.
• Lobby for Xwayland or X11 or whatever to support fractional scaling (<-- not happening).
• If this is an issue with Vtk (which I assume does the rendering), create a feature request upstream, then wait.

Additional information

There might be some cute little command line flags or environment flags that the GUI library supports to enable Wayland. Not sure.

Contribution

Please tell us if you are able to contribute (Can you develop this new feature?)
Nope, I have no idea on anything graphics library related, except that there's a couple flags you can set for Qt, GTK and Electron apps.

HI @cd-CreepArghhh

not sure if this is a Vtk problem

It is a VTK issue: https://gitlab.kitware.com/vtk/vtk/-/issues/17982

Oh right, should I close this then?

[mwestphal]

No, this issue is still valid, it just that the "fix" (its an huge feature actually, not a simple fix) must happen in VTK at some point.
