Flickering hints on Raspberry Pi

[blaggacao]

On a Rpi4, in chromium, somtimes hints flicker at a sub second frequency, for example 04 / 9 / 04 / 9 (having condigured numbers 0-9 as usable chars).

We use it in a POS setting without a backup mouse (no space, dirty envionment).

Those situations are extremely bothersome as clients queue up while I need to restart the browser to fix this.

I'd like to ask for some pointers to at least have a chance to debug into the right direction.

Thx!

Hi!

I don’t have a Raspberry Pi and have never noticed flickering, so you’ll need to fix this yourself.

What does “flicker” mean? I’m not sure I understand what “04 / 9 / 04 / 9” means.

A first step could be to go to the Options page, expand the Debug section and increase Log Level to Log or Debug. This might help you spot a loop of messages that causes something to go back and forth, which could result in flicker, I guess.

Have you read the CONTRIBUTING page? Especially the file overview will be helpful, I think.

My guess is that either the Worker is sending alternating messages causing the Renderer to flip back and forth between two states, or that there is some issue only in the Renderer that causes some kind of flicker.

Thank you, that is very helpful! Now all I have to do is be there when it occasionally occurs. 👍
