[Mali400 on ZynqMP] OpenGL rendering issues


I experience rendering issues using ARM closed user space libraries distributed with ZynqMP for Mali400 (libMali.so.9.0) and Qt Data Visualisation library running under both Wayland or EGLFS on Linux kernel 5.10.0-xilinx-v2021.2. The rendered image looks like this:

while when I switch to mesa 21.2.4 and the open source LIMA driver the scene is rendered as intended (the axes are rendered properly):

Unfortunately, the performance of the open source driver in this scene is 5 times worse (~50fps vs ~14fps) thus unacceptable.

The ARM user-space library for this device is quite old. Does the newer version of the library for this device exist? Would you have any suggestions on how to address this problem?
