Description amazingrise 2020-04-10 11:31:27 UTC
SUMMARY
Cannot change Force Font DPI on Wayland

STEPS TO REPRODUCE
1. Login to Plasma Wayland and open systemsettings5
2. Select "Font" from sidebar
3. Check "Force Font DPI", and change it to whatever 96 or 120.
4. Then plasmashell will be restarted automatically, and nothing changes.
5. Reopen other applications, nothing changes either.

OBSERVED RESULT

The font DPI is not changed.

EXPECTED RESULT

The font DPI should be changed.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Manjaro Linux
(available in About System)
KDE Plasma Version: 5.18.4
KDE Frameworks Version: 5.68.0
Qt Version: 5.14.2

ADDITIONAL INFORMATION
Comment 1 David Edmundson 2020-04-10 12:24:36 UTC
It should update on next login.

What do you mean by plasmashell will be restarted automatically? That isn't in the code.

Please also include output of env and your ~/.xonfig./kdeglobals

Sorry, the DPI of plasmashell indeed changed on next login, and all of application works normally as well. But plasmashell is restarted automatically.

Comment 4 amazingrise 2020-04-10 13:30:17 UTC
I tried to run plasmashell from terminal, and after changing DPI, it shows:

wl_registry@20: error 0: invalid global org_kde_kwin_blur_manager (50)
The Wayland connection experienced a fatal error: 协议错误
KCrash: Attempting to start /usr/bin/plasmashell from kdeinit
sock_file=/run/user/1000/kdeinit5__1
KCrash: crashing... crashRecursionCounter = 2
KCrash: Application Name = plasmashell path = /usr/bin pid = 84241
KCrash: Arguments: /usr/bin/plasmashell

 (Note: The four chinese character may be "protocol error" in English)
Thanks.
Comment 5 Patrick Silva 2020-04-10 18:15:33 UTC
on Wayland session of neon unstable, plasma crashes when a fonts setting is changed.

which as an error makes no sense as we've clearly just created object 118.
Comment 7 David Edmundson 2020-04-11 15:27:46 UTC
Kwin also resets on font changes. 

Which means we hit a problem I can reproduce here:
