STEPS TO REPRODUCE
1. run kdesu -u otheruser dbus-launch konsole
2. run dolphin from the console
3. let the screen sleep
4. wait for a few hours (can&apos;t reproduce it without a significant delay)
5. awake the screen by moving the mouse or using keyboard

OBSERVED RESULT

Dolphin crashes, but konsole doesn&apos;t crash

EXPECTED RESULT

No crash

    <thetext>I noticed that this also happens for user&apos;s own Dolphin instances as well, no need to run kdesu.

And I&apos;ve only seen this on a PC with NVidia card (currently using binary nvidia drivers 525.85.05). Haven&apos;t seen it on Intel IGP PCs so far.</thetext>

&gt; Also not restricted to Dolphin, happens with Konsole as well:

&gt; 
&gt; Seems like this is a bug it Qt5. Should I report this elsewhere?

I unfortunately don&apos;t know. This is currently filed in Dolphin which seems wrong, but I can&apos;t tell you where it belongs to. I somehow doubt that reporting this to Qt, when it seems to be restricted to KDE code, will help, but I don&apos;t have that much experience with Qt&apos;s development.

Sorry for not being of more help!</thetext>

    <thetext>I also have the same problem with 23.08.1, it&apos;s reproducible every time I turn off my monitor and turn it back on.
BTW, every time when it crashed, it was allocating a large amount of RAM (about 6GiB or more).
