I try to run SimpleMovieDemo.
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: Proper timing and timestamping of visual stimulus onset is not reliably supported at all
PTB-INFO: when running in windowed mode (non-fullscreen). If PTB aborts with ‘Synchronization failure’
PTB-INFO: you can disable the sync test via call to Screen(‘Preference’, ‘SkipSyncTests’, 2); .
PTB-INFO: You won’t get proper stimulus onset timestamps in any case though, so windowed mode is of limited use.
PTB-INFO: OpenGL-Renderer is Intel :: Intel(R) UHD Graphics :: 4.6.0 - Build 188.8.131.520
PTB-INFO: VBL startline = 1620 , VBL Endline = -1
PTB-INFO: Beamposition queries unsupported or defective on this system. 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 = 0.000000 ms [inf Hz]. (0 valid samples taken, stddev=0.000000 ms.)
PTB-INFO: Reported monitor refresh interval from operating system = 16.949153 ms [59.000000 Hz].
PTB-INFO: Small deviations between reported values are normal and no reason to worry.
PTB-WARNING: WINDOWS DWM DESKTOP COMPOSITOR IS ACTIVE! ALL FLIP STIMULUS ONSET TIMESTAMPS WILL BE VERY LIKELY UNRELIABLE AND LESS ACCURATE!
PTB-WARNING: STIMULUS ONSET TIMING WILL BE UNRELIABLE AS WELL, AND GRAPHICS PERFORMANCE MAY BE SEVERELY REDUCED! STIMULUS IMAGES MAY NOT
PTB-WARNING: SHOW UP AT ALL! DO NOT USE THIS MODE FOR RUNNING REAL EXPERIMENT SESSIONS WITH ANY REQUIREMENTS FOR ACCURATE TIMING!
PTB-INFO: All display tests and calibrations disabled. Assuming a refresh interval of 59.000000 Hz. Timing will be inaccurate!
WARNING: This session of your experiment was run by you with the setting Screen(‘Preference’, ‘SkipSyncTests’, 2).
WARNING: This means that some internal self-tests and calibrations were skipped. Your stimulus presentation timing
WARNING: may have been wrong. This is fine for development and debugging of your experiment, but for running the real
WARNING: study, please make sure to set Screen(‘Preference’, ‘SkipSyncTests’, 0) for maximum accuracy and reliability.
