I managed to get it to run properly but I still am not sure why it behaved like described in the first place. Logging in as root and then starting the app manually also resulted in the same issues as using a service to start the app. The fix was to export the variable FB_MULTI_BUFFER=3. Setting it to 2 causes screen tearing, 1 results in animations running too fast since there is no vsync.

I guess i found a solution which i don't like. I observed also two crashes of my USB stack on my Mac which are (obviously) related to this stuff. Sometimes when i start this program all my USB ports are dying and the kernel tasks runs with 100% load. I can only resurrect the USB ports by a reboot of my computer. If i connect the serial adapter on a nativ USB port, it works as intended without any errors. The USB Hub should have enough power. It is a Hub which is powered from an external power plug. For sure, i would be really thankful if anyone know a better workaround to this bug instead of utilizing one of the very rare native USB ports on a Mac, but in this case, i guess, it is an Apple problem and not an Qt related one. Thank you very much for your help Greetings Tobias

@Pablo-J-Rogina yes, I have already build qtbase and qtmultimedia with the toolchain reccomended by raspbian. If I take the same command "./configure..." changing the default toolchain with another one I have the error. I have already tested my toolchain building some test c and c++ programs.

try to play the file with "aplay"

Oh, I wasn't aware of that. Thanks for the info guys.

Here's the answer in case anyone has the same problem: The project on which i am working relies on tslib input backend to capture events from touchscreen. In average, one of six samples retreived by tslib was "noisy" hence the problems explained above. Solution was to use variance tslib plugin which gets rid of "noise samples"

@LeLev Not yet. Too many other tasks. Therefore I ask the Global Mind about this.

@nonesense said in Android "The file name must end with .xml". But its a PNG: I found out, that it is now state of the art, to put the app-icon not to "drawable", but to folders called "mipmap". Eh, why do they keep changing everything, all the time :-( Even the most basic APIs get changed constantly. Thanks for posting the correct solution, it may help more people!
