i can confirm these things happening, like the author mentioned.
i've been good with r265, since 266 shit goes bad, i've noticed mostly the problem when adding animations and loading images into it etc..
i've noticed that 266 had some double click sprite fixes, that might be the problem.
also, from 268 upwards i get random crashes from working, could be the problem with UI libs you've updated in 268.
my pc is a laptop with 980m, 8gb ram, i7 4860hq 4/8 3,6ghz, 1 tb hdd and 0.5tb ssd samsung.
pure installation of win1903 version win 10, with latest drivers from intel to nvidia & realtek music.
the problem existed prior to new drivers, so yeah.. no idea what's with that r269
