flickering in fullscreen mode

[nanu-c]

I have to investigate more about this issue

[jamet]

hey @nanu-c , it seems i don't have this problem here, could you describe a bit more? i also forgot to merge a fix_bezier branch into master, will do it now if you want to get a try with a it.... who knows ;)

[nanu-c]

yesterday i tried lpmt for visuals and had some problems but the good thing is, now I have some time :)

so it's an os related issue... but still unusable

[nanu-c]

and also the break: [drm:intel_pipe_update_end [i915]] *ERROR* Atomic update failure on pipe A (start=271143 end=271144)

[nanu-c]

Solution: use ofAppGLFWWindow window; not ofAppGlutWindow window; in main.cpp

[jamet]

@nanu-c , i changed the window manager to get rid of this problem : https://github.com/VideoMapping/lpmtX2/issues/2

could you try to reproduce it with your mods? (dysplaing a live cam feed on a external monitor, and see if the framerates drop by pressing F8 to display it)

curious if it works

[nanu-c]

I experience the same framerates drop when I use the glfw (3-8 frames/s), but if i use ofSetupOpenGL(&window,1024,768,OF_GAME_MODE); it's gone(30-50 frames/s).ofSetupOpenGL(&window,1024,768,OF_GAME_MODE); The flickering of the screen in Glut is not related to the framerate (always >50 fps).

[jamet]

I tried to modofoed to OF_GAME_MODE, but it crashes when using either glut or glfw.

I'm a bit embarressed with this @nanu-c , i can't commit this since it breaks my setup...

this seems a lot related to the hardware, if you want to compare, i 'm runnng lpmt on a core i5 with nvidia 840m here is the glfw version on my lubuntu 14-04 : ii libglfw3:amd64 3.0.4-2~trusty amd64 portable library for OpenGL, window and input (libraries) ii libglfw3-dev:amd64 3.0.4-2~trusty amd64 portable library for OpenGL, window and input (development files

and here glut :

ii freeglut3:amd64 2.8.1-1 amd64 OpenGL Utility Toolkit ii freeglut3-dev:amd64 2.8.1-1 amd64 OpenGL Utility Toolkit development files

[nanu-c]

on ubuntu mate 15.10 I have freeglut3:amd64 2.8.1-2 freeglut3-dev:amd64 2.8.1-2 libglfw3:amd64 3.1.1-1 libglfw3-dev:amd64 3.1.1-1

maybe i include a command line argument (as used here ) -glfw to use glfw instead of glut.

My hardware is a intel i3 with Intel HD Graphics 3000. I am going to try ppa:ubuntu-x-swat/x-updates ...

[nanu-c]

I solved this by installing Linux Mint ldme. But had to change some addons
