I try fsl-yocto-L3.14.52_1.1.0-ga on SabreSD board.
Then, I see there are broken textures in QT APP as attached picture.
Does anybody know how to fix this problem?
Apparently there is a shared context with framebuffer and opengl, try to resize the screen to see if this is not due to memory issue.
Also please chek this: Qt5 on i.MX6 DO's and DONT's
The resolution is 1280x720 instead of 1920x1080.
I try Freescale Yocto "imx-3.14.28-1.0.1_patch" under the same resolution, and it works fine.
BTW, I don't assign the CMA size in boot argument.
This issue is easy to reproduce to use 3.14.52 default configuration on SabreSD board.
repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-3.14.52-1.1.0_ga
MACHINE=imx6qsabresd source fsl-setup-release.sh -b build-x11
Similar issue also happens on android 5.1.1_ga with 3.14.52 kernel.
When we play 1080P picture in Gallery and slip the picture.
It is easy to observe there are broken textures.
BTW, we notice that SOC becomes very hot while running android.
For i.mx6Q, it will overheat then GPU warning messages shows to decrease clock frequency of GPU.
I guess this is the side effect that "3.14.52 release" optimizes performance of GPU driver or library.
This version has such serious defect and we can't upgrade to release 3.14.52_1.1.0_ga.
Can anybody help me?
