Kodi-rpi-19.0-2 video zoom issue

[foobar]

Hi, I just updated my RPi 4 (ARCH on armv7l) running Kodi. Apart from the expected add-on errors (outdated python 2) at first all seemed to work fine. Except for video zoom. I have lots of movies with an aspect ratio that does not fit my monitor so I usually go to video setting and change the zoom amount. But with Kodi 19 as soon as I exceed 1.00 the screen starts flickering! I could not find anything in the Kodi forums so I'm wondering if this could be a specific problem with the Kodi rpi build.

What resolution are you running in? Currently, 1080p @ 60 fps is the highest supported. 4K is considered experimental.

Currently at a test monitor 1280x720p @ 60Hz. While playing video I press OK then to Settings > Video settings > Zoom amount. View mode is Normal. As soon as the slider passess 1.00 the flickering starts. With previous Kodi 18 this did not happen.

I am running in 1920x1080 @ 60 fps. When I play this jellyfish test clip, all zoom levels are fine.

However, when I play other content, it is a mixed bag. For example, one 4k video gives flickering when i cycle through zoom levels (z key).
Normal, Stretch 4:3, and Stretch 16:9 are fine.
Zoom, Zoom 110% width, Zoom 120% width, Wide zoom, and Original size flicker for me.

Yet another, Big Buck Bunny in this case, plays all zoom levels fine except Original size.

Same problem with mp4 from my camera. I'm downloading the jellyfish now but that takes some time.

If you tail your kodi.log when experiencing the flicker:
$this->bbcode_second_pass_code('', '

I updated this ongoing post at the kodi forum with this info. Let's see what popcornmix has to say.

Hello,
I have the same flickering issues with zoom in. I added my comment (with the debug info i get --> the same as you) in the same post on Kodi's forum.
I made some tests with videos here https://jell.yfish.us/.
I played the following videos :

• jellyfish-110-mbps-hd-hevc.mkv
• jellyfish-140-mbps-4k-uhd-hevc-10bit.mkv
• jellyfish-90-mbps-hd-hevc-10bit.mkv

.
I have flickering with all of them. I also have flickering with h264 videos as well. I use the last kodi-rpi 19.0-4 package and i have the last linux-raspberrypi4 5.10.17-2 kernel.
A precision : i also tested with manjaro arm with several 5.11 kernels : mainline and not mainline --> same issues so i am almost sure this is a Kodi issue (i think)
