There are three issues with the new version of Android:
BPR material, model roughness and gloss display, HDR image resolution is extremely low, and the effect is very poor.
Move brush is very slow
Sometimes when opening the UI menu, it may stall for about 2 seconds
Nothing changed on the last version.
Maybe double check your settings (postprocess resolution?)
I upgraded from version 1.65 because the engraving function has not been updated since then, so I did not upgrade. Now I see that 1.81 has updated the engraving and tube tool functions, so I upgraded the old version and then these issues occurred
