cog Segmentation fault on STM32MP1 with modeset Renderer

[DerArtem]

Hello,

on my STM32MP1 i am getting a Segmentation fault when running cog. This seems to occour when something on the display changes. Eg, when I open a simple html website it is displayed on the screen. As soon as I click on something it crashes. Using gles renderer the issue does not occur, but I have graphic glitches.

On cog 0.12.4 this problem does not exist.

Here is a log of the segfault:
