Glitch when using warp tool

Hi all,

I encounter a very annoying display bug whenever I turn on "warping" on a layer / surface. See attached screenshot... Does it with any Millumin 4 release I've tried...

macOS Catalina - version 10.15.7 - MacBook Pro (Retina 15 pouces, début 2013)

Processeur 2,7 GHz Intel Core i7 quatre cœurs - Mémoire 16 Go 1600 MHz DDR3 - Graphisme NVIDIA GeForce GT 650M 1 Go / Intel HD Graphics 4000 1536 Mo


  • Hello @eMTv,

    This is a known issue between Nvidia graphic card's drivers and macOS. Indeed, the library Metal (the successor of OpenGL on macOS) has a problem generating big buffer of data. This concerns only machines with a Nvidia card, so machine produced before 2015. This issue only affects the warping so far.

    Of course, machines with an Intel, AMD or Apple GPU are not affected.

    We have been waiting for Apple to fix this issue on on these old machines, but now, we implemented a workaround in latest beta (4.17.b).

    Best. Philippe
