Scrivener quitting and screen redraw issues

MACOS Sequoia 15.0.1, Scrivener 3.3.6, on Macbook Air M1, 8 gb mem
I have been having redraw issues for a year now - the screen does not redraw correctly when editing until I manually scroll. Now, however, I am getting frequent crashes, which I have reported on the error screen that pops up. Rebooted machine but still happens, sometimes frequently, sometimes not. Been a user for 10 years and never had issues before. Are we waiting for an upgrade, perhaps? TIA

I experienced the same typing issues when Page View was enabled. Disabling it resolved the problem (bug!!)
