[fwd] Cursor jumps and HDMI blocked under Vista

Someone just filed this bug report over at Tux Paint’s SourceForge project…
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

Initial Comment:
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

Yeah, this doesn’t sound like an SDL problem from what I can tell. Sounds
more like some other rogue process installed about the same time that hogs
100% cpu every so often. Sadly, this sounds like a difficult to reproduce
kind of situation… where ya’d wanna see it do it from a fresh install …
especially since it sounds like SDL isn’t even initialized / dll-active and
it’s doing it.

Off topic: A coworker’s computer had a similar cursor freeze every so often
from a left over point-of-sale printer driver that was polling for hardware
every so often when none was attached. Removing the printer from control
panel -> printers didn’t help, had to actually uninstall the POS drivers.

Ask them to install it on a different Vista machine and see if they have
the same results or not.>From: Will Langford

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

Thanks. I’ve cut-n-pasted your message to the bug in Tux Paint on
SourceForge.net and dropped the priority level of the bug. Really smells
like a “not our problem” issue. And we’re still waiting to hear back on
addition details from the user.

Another odd thing they mentioned as part of the bug is that the cursor in
Tux Paint jumps around using some tools. This, sadly, is a known issue
with some of the more CPU-heavy tools (either due to math/logic complexity, or
poorly-chosen SDL_UpdateRect() calls).

What’s odd about it is that they said the cursor jumping occurs even when
Tux Paint is not running. (And it didn’t before Tux Paint was installed?
Is merely installing Tux Paint enough to cause the issues? We have both
EXE (installs stuff) and ZIP (runs self-contained from a folder) versions…
do both exhibit this behavior? Etc. etc.)

So… Not enough info to know whether it’s something we can avoid, but I’m
guessing it’s not our problem. (Tux Paint’s or SDL’s.)

Hi Bill,

Just thought I’d let you know I got my hands on a Toshiba Satellite
A215-S7437 running Windows Vista and I didn’t seem to have any
problems running Tux PaintOn Fri, Dec 5, 2008 at 4:46 PM, Bill Kendrick wrote:

Thanks. Does it have any HDMI displays? :slight_smile:

Also, side-note… someone asked me if Tux Paint runs on 64-bit Vista.
I have no idea… I don’t see why not. 64-bit Vista can run 32-bit apps,
right???

No, only a built-in LCD display and a VGA signal out port.

Yes, it should run.On Mon, Dec 15, 2008 at 7:16 PM, Bill Kendrick wrote:
