上記のシステムを用いて,Psychtoolbox3のデモプログラムの動作を試みていますが,同期エラーが解決できません。ソースコードは編集せずにそのまま使用しています。以下,エラーメッセージです。
Tried to prepare a new configuration phase via PsychImaging('PrepareConfiguration'), but did not finalize the previous phase yet.
You must call the PsychImaging('OpenWindow', ...); command at least once to open an onscreen
window according to the provided settings, before you can specify settings for additional onscreen windows.
The most likely reason you see this error message is because your script aborted with some error
before it managed to open the onscreen window. In that case it is best practice to execute a 'clear all'
command at the Matlab/Octave prompt before you restart your script.
I will restart configuration now and forget the previously made PsychImaging('AddTask', ...); settings.
警告: Tried to prepare a new configuration phase, but you did not finalize the previous phase yet!

PTB-INFO: This is Psychtoolbox-3 for Microsoft Windows, under Matlab 64-Bit (Version 3.0.19 - Build date: Feb 20 2023).
PTB-INFO: OS support status: Windows 10 (Version 10.0) supported and tested to some limited degree.
PTB-INFO: Type 'PsychtoolboxVersion' for more detailed version information.
PTB-INFO: Most parts of the Psychtoolbox distribution are licensed to you under terms of the MIT License, with
PTB-INFO: some restrictions. See file 'License.txt' in the Psychtoolbox root folder for the exact licensing conditions.
PTB-INFO: For information about paid support, support memberships and other commercial services, please type
PTB-INFO: 'PsychPaidSupportAndServices'.
PTB-ERROR: Mismatch between requested display swap interval 1 and actual swap interval 0! Synchronization of Screen('Flip') to display refresh will likely malfunction!
PTB-ERROR: This is either a bug in your graphics driver or system setup, or some misconfiguration in the display setting control panel of your system. See 'help SyncTrouble' for more info.
PTB-INFO: The detected endline of the vertical blank interval is equal or lower than the startline. This indicates
PTB-INFO: that i couldn't detect the duration of the vertical blank interval and won't be able to correct timestamps
PTB-INFO: for it. This will introduce a very small and constant offset (typically << 1 msec). Read 'help BeampositionQueries'
PTB-INFO: for how to correct this, should you really require that last few microseconds of precision.
PTB-INFO: Btw. this can also mean that your systems beamposition queries are slightly broken. It may help timing precision to
PTB-INFO: enable the beamposition workaround, as explained in 'help ConserveVRAMSettings', section 'kPsychUseBeampositionQueryWorkaround'.
PTB-WARNING: Couldn't even collect one single valid flip interval sample! Sanity range checks failed!
PTB-WARNING: Could be a system bug, or a temporary timing problem. Retrying the procedure might help if
PTB-WARNING: the latter is the culprit.
PTB-WARNING: Couldn't collect valid flip interval samples! Fatal VBL sync failure!
PTB-WARNING: Either synchronization of doublebuffer swapping to the vertical retrace signal of your display is broken,
PTB-WARNING: or the mechanism for detection of swap completion is broken. In any case, this is an operating system or gfx-driver bug!
WARNING: VBL Calibration run No. 1 failed. Retrying...

WARNING: Will enable VBL busywait-workaround before trying final VBL Calibration run No. 3.
WARNING: This will hopefully work-around graphics driver bugs of the GPU sync-to-retrace mechanism. Cross your fingers!
PTB-INFO: OpenGL-Renderer is NVIDIA Corporation :: NVIDIA GeForce RTX 3070/PCIe/SSE2 :: 4.6.0 NVIDIA 537.13
PTB-INFO: VBL startline = 1080 , VBL Endline = 1079
PTB-INFO: Measured monitor refresh interval from beamposition = 16.667161 ms [59.998220 Hz].
PTB-INFO: Beamposition queries are supported, but disabled. Using basic timestamping as fallback:
PTB-INFO: Timestamps returned by Screen('Flip') will be therefore less robust and accurate.
PTB-INFO: Measured monitor refresh interval from VBLsync = 16.664528 ms [60.007700 Hz]. (50 valid samples taken, stddev=0.176295 ms.)
PTB-INFO: Reported monitor refresh interval from operating system = 16.666667 ms [60.000000 Hz].
PTB-INFO: Small deviations between reported values are normal and no reason to worry.
PTB-INFO: ==============================================================================================================================
PTB-INFO: WINDOWS DWM DESKTOP COMPOSITOR IS ACTIVE. On this Windows-10 or later system, Psychtoolbox can no longer reliably detect if
PTB-INFO: this will cause trouble for timing and integrity of visual stimuli or not. You might be just fine, or you could be in trouble.
PTB-INFO: Use external measurement equipment and independent procedures to verify reliability of timing if you care about proper timing.
PTB-INFO: ==============================================================================================================================
PTB-INFO: Enforcing script abortion and restoring desktop by executing Screen('CloseAll') now!

SyncTrouubleREASONS FOR FAILING THE SYNC TESTS AND HOW TO FIX THEMに書かれている内容は一通り試しましたが,挙動は変わりません。エラー原因を教えていただけますと幸いです。
よろしくお願い致します。
