Chromium antialiasing half-broken on Orange Pi 5 Plus with GPU acceleration enabled

[Ivgal]

Hi everyone! I have recently bought an Orange Pi 5 Plus (16 GB RAM) and installed Armbian (the Pi Plus version). Then I enabled GPU hardware acceleration, as suggested on the Armbian download page, which then updated chromium and other things to the rkmpp versions. Now, if I start chromium under Wayland (tried Sway, Gnome, and KDE), the hardware acceleration works nicely, so I get good FPS on e.g. WebGL aquarium, and similar things. However, the antialiasing of some items on the screen does not seem to be working. Antialiasing in WebGL seems off as well. You can see an example in the attached screenshot. Here's what I have tried so far:

 

• Before installing GPU acceleration packages from PPAs: antialiasing is good, video + WebGL very slow
• After installing, antialiasing is not working for some items, but video and WebGL performance is good. Terminal output from chromium:

• When running Chromium with malirun (I understand that this makes it use blob drivers for Mali), the antialiasing is working again, but attempting to open chrome://gpu leads to a temporary freeze and the following console output. In addition, the keyboard and general interaction with the browser seems laggy, despite good WebGL performance:

Since I would like to use the OPi5 Plus for some browsing and related things, is there something that I can do to make antialiasing work? Thanks a lot in advance!
