Resize scaling

[whossname]

Using the example project I've found that if I set resizeable to true and change the size of the window everything seems to scale with the opposite magnitude relative to the initial size. So if I double the width of the window the width of the content halves.

I am using Ubuntu 16.04 with unity and the glfw driver.

I'll take a look, but it will be a few days, maybe to next week...

[boydm]

Is this with the 0.7 driver or 0.8?

I just tried it with the 0.6 driver on Ubuntu 16 and it worked ok. Anything else you can tell me about your system would also be helpful.

[whossname]

I was just playing with it, so there's no rush. After running using the 0.8 driver and seeing the problem, I built the driver locally to try and figure out what was happening. Obviously, I couldn't figure it out.

What would you like to know? I'm not really sure what is relevant, so here are a few commands:

             configuration: ansiversion=5 status=nodisc

[whossname]

Just ran it using the following in mix.exs for deps, getting the same problem:

      {:scenic, "~> 0.6"},
       {:scenic_driver_glfw, "~> 0.6"},

@boydm and @whossname
I can confirm this problem in example app on 0.8 version. It's really weird. @whossname which OS/distribution you have?

[whossname]

Ubuntu 16.04

[boydm]

I'm traveling for a few days, so will need a bit of time to figure it out. I'm running Ubuntu 16.04 in a VM (parallels) on a Mac, and don't see the problem, so that doesn't really help.

Hey - what happens when you expand it vertically? Does it squish shorter too?

[Aely0]

Spun up Ubuntu 18.04 in a VM with scenic and scenic_driver_glfw being 0.8. Essentially the scene reacts in inverted fashion to a resize on both axis, getting squished when window size increases and vice versa.

[whossname]

I saw the same behaviour when I tried the 0.6 and 0.7 drivers, but I'm wondering if I installed the driver correctly now.

If you compile the driver locally and use that in your mix file, does it use the driver built in the privfolder?

[boydm]

What resolution monitor do you use?

This is almost definitely because the screen size and the frame buffer size are different. This works fine on the Mac with a retina display but the signaling is probably different under Ubuntu. I'm running Ubuntu under an emulator (parallels) on my mac, and I'm sure they are coming out the same size.

This is just a matter of catching the right signaling from the GLFW driver. Shouldn't be a big deal once I can get a repo locally.

What resolution monitor do you use?

My resolution is 1280 x 1024

screen #0:
  dimensions:    1280x1024 pixels (337x270 millimeters)
  resolution:    96x96 dots per inch
  depths (7):    24, 1, 4, 8, 15, 16, 32
  root window id:    0x170
  depth of root window:    24 planes

btw. How about work on LiveCD/LiveDVD/LiveUSB Linux distribution? There are lots of distributions which allow such option to test how they are working on you hardware without any emulations.

[whossname]

$ xdpyinfo | grep resolution
  resolution:    96x96 dots per inch

$ xrandr | grep ' connected'
eDP1 connected primary 1920x1080+3840+0 (normal left inverted right x axis y axis) 382mm x 215mm
DP1 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 544mm x 303mm
HDMI1 connected 1920x1080+0+0 (normal left inverted right x axis y axis) 544mm x 303mm

@boydm I was taking a look at those parts:

1. c_src/main.c - following main/2 I have found and debugged reshape_framebuffer/3 and reshape_window/3
2. c_src/comms.c - from main.c file I followed msg_reshape_t struct and send_reshape/4 function in which I found how you send communication and after quick remind I did not had any problem with sending my own custom messages
3. lib/glfw/input.ex - following handle_port_message/2 after some research (I was need to find <<name::float-size(32)-native>>) I had no problem with receiving my own custom messages

As you can see I got basics of sending messages, so next debug would be much faster as I do not need to study those code parts again. Below I would show what I found so far. I know C in general, but I do not have an experience with nanovg, so I'm not sure if what I found would be helpful for you …

Always 1.0 for me:
https://github.com/boydm/scenic_driver_glfw/blob/e744f89a929278be41339b25364ea84768674359/c_src/main.c#L67

Same here:
https://github.com/boydm/scenic_driver_glfw/blob/e744f89a929278be41339b25364ea84768674359/c_src/main.c#L69

Same goes to screen_factor in when send_reshape/4 (in C) is handled in Elixir:
https://github.com/boydm/scenic_driver_glfw/blob/e744f89a929278be41339b25364ea84768674359/lib/glfw/input.ex#L166

I'm curious why you are passing same values here:
https://github.com/boydm/scenic_driver_glfw/blob/e744f89a929278be41339b25364ea84768674359/c_src/main.c#L72
Note: You previously assigned value w to p_data->context.window_width and h to p_data->context.window_height, so passing two variables storing same value does not makes sense, but maybe it has something with pointers (* in declaration/cast), but I'm not sure … I did not used C for long time and also I do not know if nanovg have something like multithreading and changes pointer data in background.

---

Assuming that frame and window should have equal height and width then their values were correct. I have checked them when taking a look at frame_ratio.

---

I'm almost sure that it's expected and it would not be really helpful for you, but it was just my first try. Please let me know if I have missed resize handling code (except nanovg directory which I did not checked yet I did not found anything more related to resizing) and what data would you like to have debugged. As it's not taking me lots of time most probably I would be able to respond quickly.
