This does not sound like an SDL problem.
This problem sounds very bizarre, and there’s a good reason behind that.
This problem – although its manifestations and triggers have been and
always will be extremely vague – has been on horizon for Vista users
for quite some time. I’m surprised as an interested party to FOSS
issues that I haven’t seen a lot more bug reports relating to it so
far. In fact, I haven’t seen any. But this sounds like it might just
be that. Here are some excerpts from the above article:
“Shamelessly pandering to the Big Media copyright holders, Vista
automatically degrades so-called ‘premium’ content such as high
definition movies and audio tracks when they are output to less than
bleeding-edge new devices that don’t happen to support Intel’s
High-bandwidth Digital Content Protection (HDCP) DRM scheme. It
apparently does this even if the media files being played are not
copyright protected commercial media but the users’ own home movies or
music they’ve recorded in high-definition format, Gutmann said.”
Many months ago I would have been extremely interested in researching
the causes of any effect that persists after a FOSS application is
uninstalled from a system. Given that Vista can’t seem to do
anything right, I can’t even manage to bat an eyelash at this news.
Good luck identifying the arbitrary circumstances which trigger

This almost certainly must be something going on at the SDL-level.
Any ideas? (I’m especially surprised by problems that continue to occur
even when the app is not running, and has been uninstalled…!!!)

Summary: Cursor jumps and HDMI blocked under Vista
Under Vista, any version, the cursor jumps with some tools and HDMI output is blocked even with program not running. Cursor problem is very noticeable in Caleidoscope and Calligraphics, both unusable. Cursor jumps are also noticed when TuxPaint is not running, or even after uninstall. Video driver or card seem affected. Running in XP mode or under administrative rights have no positive effect.
The same program under native XP runs smoothly
