My display shortly fades out and returns when starting any native app

This behaviour is quiet annoying. It does not impact android apps. It started some time ago, might be caused by improper use of the app qCommand from openrepos. I tried to fix it by resetting mcetool by deleting /var/lib/mce/builtin-gconf.values, but it did not help. I hope someone can help me with this.

I use version 3.2.1.20 on XA2 Ultra

No idea what the problem is, but regarding that mce settings file:

Do not edit/remove it manually, instead use: "mcetool --reset-settings"

[Or if you for some reason need/have to, then do "systemctl stop mce" before modifying and "systemctl start mce" after you are done with changes.]

Also, on a very cursory glance in qCommand source tree, the only mce related thing I could spot is that it fiddles with never-blank mode - which is almost certainly not what it should be doing.

actually i did stop and start the mcetool. also i am not sure if the problem is really related to this, i only suspect it, due to the closeness in time of its occurence. meanwhile i observed repeated fading of the display. does nobody have an idea, what could be the cause?

It does sound a bit like the issue I'm having with flash/flicker/blanking Silica apps.

indeed, thanks for pointing that out. Sadly, also no solution there. :(
