Bug 778

Summary: Maximum Window width of 4096
Product: SDL Reporter: Derek Weitzel <djw8605>
Component: videoAssignee: Ryan C. Gordon <icculus>
Status: RESOLVED FIXED QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: patmandin
Version: 1.2.10Keywords: target-1.2.14
Hardware: x86   
OS: Linux   

Description Derek Weitzel 2009-08-11 12:17:09 UTC 
Window Manager: xorg-x11-twm-1.0.1-3.1

Running through Xdmx.  The same application could expand to the full screen using GLUT (freeglut).


Overview: 
While running on a very high resolution display, discovered the maximium width of the window is 4096.

Steps to Reproduce:
1) Create a window, expand it to further than 4096 (or attempt to)

Actual Results:
Application stops sending window resize events when trying to widen the window.  Height resize still creates event.

Expected Results:
Window to continue to resize.

Build Date & Platform:
xorg-x11-twm-1.0.1-3.1 on Centos 5.3

Additional Builds and Platforms:
Does not occur when using GLUT (freeglut).

Additional Information:
This display is using Xdmx for distributed desktop (3 render nodes, 1 head node).  The resizing to full screen works for Firefox, GThumb, freeglut applications.

Forgot to mention, this is an OpenGL program.
Comment 2 Ryan C. Gordon 2009-09-13 16:33:35 UTC 
Tagging this bug with "target-1.2.14" so we can try to resolve it for SDL 1.2.14.

Please note that we may choose to resolve it as WONTFIX. This tag is largely so we have a comprehensive wishlist of bugs to examine for 1.2.14 (and so we can close bugs that we'll never fix, rather than have them live forever in Bugzilla).

Comment 3 Patrice Mandin 2009-09-14 10:48:51 UTC 
As it is an OpenGL application, I suspect the hardware (and/or OpenGL driver) to not support an OpenGL context with dimension above 4096.
Comment 4 Derek Weitzel 2009-09-14 11:15:13 UTC 
Freeglut OpenGL applications work at full screen.
Comment 5 Sam Lantinga 2009-09-21 02:48:11 UTC 
This is fixed in subversion, thanks!
