[SDL] Bugs in SDL

[Steven Brown]

I've been trying to use SDL to write a few cross-platform windowed GL 
programs and have run into a few bugs.  These are on a recent full install 
of Redhat 7.1 with a Voodoo3 in KDE with both SDL 1.2.1 and the 
RedHat-supplied 1.1.7.  GL/glut applications work well on my system, so I 
assume they are SDL-specific problems.

Minimizing windowed GL things like 'testgl' or 'SDLgears' comes close to 
locking up X.  X responds so slow it takes 20 seconds to maximize the 
window (at which point it works fine again).  This is not a problem with 
glut applications.

Maximizing a window results in it being the right size, but not moving to 
0,0, so most of the window winds up off the screen (The window's orign 
stays the same in other words).  This is not a problem with glut 
applications either.

Any windowed SDL GL program causes the gamma level to change from what it 
is set to (see 'xgamma') until a different window is selected at which 
point it resets to the correct levels.  Selecting the SDL window again does 
not mess up the gamma levels again.  Interestingly, glut programs cause the 
gamma to change for a split second when they first load, but do not stay 
wrong like they do with SDL.

Also, when I try to get 1.2.1 working in cygwin, I can get it to build and 
install ok, and it compiles the tests, but when trying to run a test, 
Windows pops up an error dialog about not being able to find SDL.dll.  I 
tried installing it with different prefixes (so I have SDL.dll in /lib, 
/usr/lib, /usr/local/lib, etc.) but no good.  Not having 'ldd' or 
'ldconfig' on cygwin, I can't figure out further what the problem is.  It 
looks like it should work, so I'm confused.
