V2.3.4 works fine

Research direction

Start with the attached armbianEnv.txt and reproduce the issue on CB1 with Manta M4P and TFT35 using V3.0.0, then compare the behavior with V2.3.4. Trace why the image loads but KlipperScreen is replaced by a black screen and cursor; done means KlipperScreen renders normally on the reported hardware.
