Hi Mario and friends, I’m using macOS 10.14.6 Mojave. MATLAB 9.6 (R2019a) Update 8 MacBook Pro (15-inch, 2017) I just upgraded to Psychtoolbox 3.0.17. Was that a mistake? (I did read the release notes, which require Catalina. But if we absolutely need Catalina, shouldn’t UpdatePsychtoolbox at least issue a warning about the OS version? The error messages I got are not at all suggestive of having the wrong OS version.) Error below. I’d be grateful for help or advice.

I just spent 2 hours going through our code and there has not been any change in the relevant code that could cause this error. The only thing that changed is that the build system is now Catalina 10.15.7 instead of High Sierra 10.13.6, and the SDK is now the Catalina SDK instead of the Mojave SDK. This is certainly yet another Apple macOS bug, maybe this time in the Apple XCode SDK’s. So let’s see what the iToys company screwed up this time. Restart Matlab, or “clear all”. % Let’s skip error detection and see how far we get: Screen(‘Preference’,‘ConserveVRAM’, 512); % Run some demo, e.g.: InitializeMatlabOpenGL(, 1, 1); PerceptualVBLSyncTest or LinesDemo or DrawSomeTextDemo. Do they work? Then you can do this in the command window or a script: PsychDebugWindowConfiguration; w = Screen(‘Openwindow’, 0); glClear(GL.COLOR\_BUFFER\_BIT); glClearColor(0.5, 0.5, 0.5, 1.0); glClear(GL.COLOR\_BUFFER\_BIT); v = glReadPixels(0, 0, 1, 1, GL.RED, GL.UNSIGNED\_BYTE) glPixelStorei(GL.UNPACK\_ALIGNMENT, 1); glClearColor(1,1,1,1); glGetString(GL.VENDOR) glGetString(GL.RENDERER) glGetString(GL.VERSION) glGetString(GL.EXTENSIONS) sca; And let me know on which one it aborts with an OpenGL error. These are the only calls that could in theory trigger an OpenGL error in this scenario, but in practice none of them can, except if Apple screwed up badly - which is of course their thing. [Work time spent so far to diagnose Apples screwup: 3 hours] -mario ---

dear mario many thanks. I restarted MATLAB. All the suggested tests run fine, with no error. Here’s the print out. Just in case, I reran UpdatePsychtoolbox, and got the same error, below. Any more tests I can run? best denis p.s.

Ok, that’s annoying. So with the error checking during Screen(‘Openwindow’) disabled - that’s what that first **Screen(‘Preference’,‘ConserveVRAM’, 512);** does - ‘OpenWindow’ completes without apparent malfunctions, showing the nice new welcome logo, passing all other non-OpenGL correctness and timing tests. Demos seem to run without visual artifacts or apparent trouble judging from the output? And the specific sequence of the only OpenGL commands during ‘OpenWindow’ which could in theory trigger an error do not trigger an error when executed manually from the Matlab prompt outside the context of ‘OpenWindow’. This problem has some similarity to the one reported in: [Screen() Failure](https://psychtoolbox.discourse.group/t/screen-failure/3499) for macOS Sierra 10.12 but also possibly and some remote similarity to [MAC OS PsychError\_InvalidWindowRecord](https://psychtoolbox.discourse.group/t/mac-os-psycherror-invalidwindowrecord/3557) for Catalina although the latter one has too little information and is not quite identical. Can you check if demos like the ones you ran here, LinesDemo, DrawSomeTextDemo, etc. do work after a restart of Matlab without using the `Screen(‘Preference’,‘ConserveVRAM’, 512);` ie. with regular error handling enabled? I’d assume they fail as well, because what happens inside UpdatePsychtoolbox is just opening a hidden onscreen window and drawing a little text string - this to trigger a potential update of the fontconfig database if needed. It executes this sequence : > Assuming this all fails as well, because it is some weird interaction bug between OpenGL calls and other code that has nothing to do with OpenGL and should not cause such an error at all, it is time to get out the big guns. The following Technical note teaches you how to install and use Apples OpenGL Profiler, attach it to the running (freshly started!) Matlab process, set a breakpoint on OpenGL errors and start tracing. Then run a test sequence: PsychDebugWindowConfiguration; w = Screen(‘Openwindow’, 0); sca; The profiler should halt Matlab execution once the OpenGL error is encountered during ‘Openwindow’ and the trace should hopefully point in the general direction of where the problem happens. > **[Technical Note TN2178: Real world profiling with the OpenGL Profiler](https://developer.apple.com/library/archive/technotes/tn2178/_index.html#//apple_ref/doc/uid/DTS40007990-CH1-SECTION1)** ---

Dear Mario Thank you. Things have changed (for the better), though I don’t understand why. Restarting MATLAB and running just the code you pointed me to from UpdatePsychtoolbox produces the same error that I reported from UpdatePsychtoolbox. INTERNAL PSYCHTOOLBOX ERROR error: Psycherror\_OpenGL general description: OpenGL call returned an error specific description: GL\_INVALID\_FRAMEBUFFER\_OPERATION\_EXT module name: Screen subfunction call: OpenWindow file name: /Users/kleinerm/projects/OpenGLPsychtoolbox/Psychtoolbox-3/PsychSourceGL/Source/Common/Screen/PsychTextureSupport.c function name: PsychCreateTexture line number: 166 Something went wrong with text renderer setup.

Thus, the ONLY error I now find is the section of UpdatePsychtoolbox fails when run alone without Screen(‘Preference’,‘ConserveVRAM’, 512); I don’t understand why the error I originally reported for UpdatePsychtoolbox is gone. It seemed solid when I reported it. Now it’s gone. Now the error appears only when I run the section of UpdatePsychtoolbox code that you pointed me to: | if ~IsLinux | | | --- | --- | | | % If this is not Linux, then open an invisible onscreen window and | | | % draw some dummy text with the plugin text renderer, just to | | | % trigger a (re-)build of the fontconfig cache if that should prove | | | % neccessary. Such a rebuild can take many seconds to even minutes | | | % and looks to the user like a hang, so do it here, with proper | | | % warning. We skip this on Linux, as the OS will take care of | | | % proper rebuilds appropriately, so we don’t expect to ever run | | | % into this problem: | | | fprintf(‘Trying to trigger an update of the fontconfig cache if that should prove neccessary.\n’); | | | fprintf(‘This may take a couple of seconds, or sometimes even minutes.

There hasn’t been any change wrt. macOS from my side. Does UpdatePsychtoolbox work even after you restart Matlab? There isn’t anything in UpdatePsychtoolbox apart from that snippet that touches OpenGL, so they should behave the same under same starting conditions. My best guess would be to try the snippet with the ‘WindowShieldingLevel’ calls removed. Those make sure the “onscreen window” is created in an invisible state, as we don’t want to popup a window that serves no real purpose and just distracts or confuses. Maybe the iToys company broke something wrt. rendering into hidden windows if the 10.15 SDK with which the mex file was build it more recent than the \<= 10.14 macOS it is running on? -mario ---

Ok, fixed in latest beta release. Needless to say it was another screwup by Apple which we work around now. macOS Catalina is a gift that keeps giving… The last two weeks alone created a loss of 1000 Euros in unpaid work time spent dealing with Apples screwups after accounting for a user paying for priority support. If not many more labs will start contributing soon by buying our new services, and Apple continues to suck as much as they did the last 10 years, supporting macOS really makes no business sense, except as a gigantic charity act. And i’m getting tired of charity acts. So far the uptake is underwhelming. But lets see what next year brings…
