• Bug report ID | echo $G_HW_UUID

Steps to reproduce

1. Fresh Installed bookworm from image
2. Installed Chrome + some other apps (see below)
3. Launch RDP and login (root)
4. Load Chrome, but Chrome window doesn’t display correctly https://i.ibb.co/mGL6Psc/image-2024-02-03-134719999.png

Expected behaviour

• Install Chrome
• load Chrome
• Chrome Window should display correctly

Actual behaviour

• Chrome window is gibberishly displayed. It appears Chrome itself may be working (moving the mouse and clicking on where I assume the Chrome menus are suppose to be seems to change the corrupted displayed pixels, and closing the window works fine - so I assume it’s bringing up menus, etc. but just not displaying them correctly.

Extra details

1. The Chrome Window Menu appears to work: https://i.ibb.co/7y1zbwk/image-2024-02-03-140827349.png, just not the Chrome menu or display
2. I uninstalled Chrome and installed Firefox for the first time, which didn’t initially have this issue. Then I uninstalled Firefox and re-installed Chrome to recheck Chrome (but still has the issue). So I uninstalled Chrome to go back to Firefox, and now FiIrefox has this pixelated window issue - seems like a graphics/memory management setting issue not necessary with Chrome itself?
3. GPU/RAM Memory Split = Desktop (RPi 4B 8GB)
4. Rebooting makes no difference and re-installing the browsers make no difference
5. Other installed apps:

• Open SSH Client & Server
• Samba Client + Server
• ALSA
• X.Org
• FFmpeg
• LXDE,
• XRDP
• I2C (for UPS)
• Fail2Ban
• Logrotate
• RSlog
• Webadmin
• Python 3

5. Chrome works fine on bullseye (RPi 4B 8GB)

• cat /boot/dietpi/.version
  G_DIETPI_VERSION_CORE=9
  G_DIETPI_VERSION_SUB=0
  G_DIETPI_VERSION_RC=2
  G_GITBRANCH=‘master’
  G_GITOWNER=‘MichaIng’
• echo $G_DISTRO_NAME $G_RASPBIAN
  bullseye 0
• name -a
  Linux Pi-2A 5.10.103-v8+ #1529 SMP PREEMPT Tue Mar 8 12:26:46 GMT 2022 aarch64 GNU/Linux
• ppkg --print-architecture
  arm64
• echo $G_HW_MODEL_NAME
  RPi 4 Model B (aarch64)

hmmm just checked on RPi5, there it seems to be fine

Need to check on RPi4 next

[qlander]

check bookworm on the pi4, since on the bullseye on pi4 works fine

[Joulinar]

I did checked the Bookworm image on RPi5 already.

Can you try following

• dietpi-config
• 1 : Display Options
• 1 : Display Resolution
• 1080p : 1920 x 1080
• exit and reboot

This is working on my test

[qlander]

That seems to have fixed it. Is it not the default setting?

Strange that using vc4-ksm-v3d or vc4-flms-v3d (both OpenGL 1920 x 1080) causes the issue, but fixed with 1090p: 1920 x 1080.

Thanks for the assistance
