Please run the game with the environment variable GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage,GPU-load, num-bytes-moved,buffer-wait-time,num-compilations+num-shaders-created and attach a screenshot of the game window taken just after a freeze occurred.
Um, my Linux knowledge is limited with this. I have minecraft-launcher in my /usr/bin folder, so what I did was I put the following in the terminal and hit enter
/usr/share/minecraft/ GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT-usage,GPU-load,num-bytes-moved,buffer-wait-time,num-compilations+num-shaders-created
The game loaded up but I don't know if what you want is working.
