Bug 3618

Summary: SDL 2.04 fails to render when Nvidia's "fast" vsync setting is enabled
Product: SDL Reporter: mattreecebentley
Component: videoAssignee: Ryan C. Gordon <icculus>
Status: ASSIGNED --- QA Contact: Sam Lantinga <slouken>
Severity: normal    
Priority: P2 CC: icculus
Version: 2.0.4   
Hardware: x86_64   
OS: Windows 7   

Description mattreecebentley 2017-03-26 23:29:38 UTC 
mingwx64 6.3 or 5.1
win7 x64
8gb ram
core2duo e8500
nvidia gtx 750
latest mainstream drivers as of 23/3/2017

Using "fast" vsync setting in nvidia graphics driver settings means SDL2 displays nothing onscreen. Other aspects (sound etc) continue.

Since I can't get 2.05 to run on my system (see timer bug) I cannot evaluate whether this bug is still present in it.
Comment 1 Ryan C. Gordon 2017-03-27 05:41:24 UTC 
It's possible we fixed this, so we'll sort out the timer bug first and revisit this, but: are you rendering with OpenGL, Direct3D? The SDL render API or direct OpenGL calls, etc?

Comment 2 mattreecebentley 2017-03-27 07:03:16 UTC 
Yeah, straight SDL API, opengl-capable window. Will try a minimal test case for the other one and get back to you.
Comment 3 mattreecebentley 2017-08-13 22:36:02 UTC 
Confirming that this still occurs with the most recent build release (tested via the auto-build for VCC) with 'Fast' vsync as of today.

Hello, and sorry if you're getting dozens of copies of this message by email.

We are closing out bugs that appear to be abandoned in some form. This can happen for lots of reasons: we couldn't reproduce it, conversation faded out, the bug was noted as fixed in a comment but we forgot to mark it resolved, the report is good but the fix is impractical, we fixed it a long time ago without realizing there was an associated report, etc.

Individually, any of these bugs might have a better resolution (such as WONTFIX or WORKSFORME or INVALID) but we've added a new resolution of ABANDONED to make this easily searchable and make it clear that it's not necessarily unreasonable to revive a given bug report.

So if this bug is still a going concern and you feel it should still be open: please feel free to reopen it! But unless you respond, we'd like to consider these bugs closed, as many of them are several years old and overwhelming our ability to prioritize recent issues.

(please note that hundred of bug reports were sorted through here, so we apologize for any human error. Just reopen the bug in that case!)

Thanks,
--ryan.

Bug still present in 2.08 and with latest nvidia drivers in Win7 x64
Comment 6 Ryan C. Gordon 2018-08-07 01:12:40 UTC 
Okay, I'll try to reproduce this here.
