iMovie 10.1.13 upgraded uninstalled 2x. Start to edit movie, then tools break into colored blocks on screen and not responsive,

Chris Torrence,

Apparently disabling checked accessibility options only works in some cases. I wonder if a graphics card upgrade is necessary with iMovie 10.1.13 and Catalina, in view of the several reports that have been posted about graphics issues. We'll just have to wait and see if Apple fixes it with future updates. At least you were able to downgrade and get it working.

I think it may be related to the graphics system? I have the same problem on this machine with both Mojave and Catalina:

iMac (27-inch, Late 2013), 3,5 GHz Quad-Core Intel Core i7, 32 GB RAM, NVIDIA GeForce GTX 775M 2 GB

Tried to reinstall Imovie, tried new library, tried library with only one project, tried deleting prefs etc. No difference.

Tried the same library with only one project on this with Mojave: Macbook Air (13-inch, Mid 2012), 2 GHz Intel Core i7, 8 GB, Intel Graphics 4000. No problem!

Apple support in Denmark? Not really...

I get these colored blocks (they're actually pink on my screen, but appear to be green in the screenshots I took) when I want to use the menu bar inside a project in iMovie 10.1.13. I then updated to Catalina, but the problem remained. It only happens when editing a project, not in the overview screen. In this state, the software is not usable any more. Any ideas? Don't think it is possible to downgrade to the last working version.

I see the same behavior. iMovie 10.1.13 on a MacBook Pro (15 inch), macOS 10.14.6. iMovie worked fine before the upgrade. Now the screen is filled with graphics tearing and large blocks. iMovie is completely unusable. Closing the app makes the problem go away. Tried rebooting, tried using a different/new iMovie library. Nothing helped.

I know, annmou. Now Apple Support Denmark know too :-) But as suspected they can't tell how or when they (or even I) will be able to solve it. Does anybody know, if the previous version of Imovie works under Catalina?

I've been working a lot in my libraries "avoiding" the issue until I find impossible to continue. Now I downgrade to 10.1.12 using Time Machine and my older iMovie libraries are no longer compatible! WTF!!! Hope the update with the solution comes fast.

What's happening with Apple?!!!

NO, *** la versión anterior de Imovie a 10.1.13 tampoco funciona, lo intenté y los menus siguen apareciendo distorsionados.

Lo que no he probado porque me d miedo es ir a una version anterior a mac os catalina, he actualizado a mac os catalina y ahí me quedo ,espero que se solucione pronto lo de imovie 10.1.13

Yes, the only solution that appears to work (as described in several replies above):

Go to System Preferences->Accessibility->Display and turn off both reduce transparency and increase contrast.

Crazy that Apple does not have this tip in their support site for resolving iMovie issues.

Nice to know I not the only one having problems..How do I  reverted to iMovie 10.1.12?

Hopefully, you have TIME MACHINE running?

That's great! :) Glad you got it working again.

johncri,

Good that you can now read the menu's. Strange that this happens with 10.1.13.

I am experiencing the same exact issues. Hopefully they have a fix soon.
