OS:

# uname -a
Arch Linux 4.18.9-arch1-1-ARCH #1 SMP PREEMPT Wed Sep 19 21:19:17 UTC 2018 x86_64 GNU/Linux
*with wayland*

Steps to reproduce

• install dependencies (I was just missing community/glfw-wayland 3.2.1-1)
• generate a new app with mix scenic.new
• run mix deps.get
• run scenic.run

Expected Behavior

The example app window shows up with correct positioning.

Actual Behavior

The rendered output only takes up a quarter of the whole window. The areas for buttons and drop downs are positioned correctly which means to have to click into the empty black part of the window to hit something.

Stack Trace

Sadly there is not a lot to see here, just a single message from GLFW.

mix scenic.run        
GLFW error 65544: Wayland: Focusing a window requires user interaction

Additional Comments

• I have a 4k screen, maybe thats a problem?

I just had the exact same problem, but I'm running an up-to-date version of Debian Stretch (with X11), with a 1080p monitor.

I can provide more information on request, if necessary : )

Probably related: ScenicFramework/scenic_driver_glfw#10 - looks like there are some wrong calls on glfw for both Wayland and X11 on Linux.

@boydm Can you please let me know where resize is handled? I'm not sure where I should search it in code … Maybe I could debug it …

[boydm]

OMG. I think I just solved this. Only two years later.

When I push the next update to the v0.11 branch (hopefully later this week) this issue should be fixed.

[boydm]

OK. This should be fixed in v0.11.0-beta.0 and the scenic_driver_local render. Can somebody please confirm and close the issue if you agree?

Many thanks

[Eiji7]

@boydm Yes, I tested and it works now. Many thanks!
