Bug ID: 368138
Summary: Kdevelop hangs at start and uses one cpu at 100% when
with hi dpi settings
Product: kdevelop
Version: 5.0.0
Platform: openSUSE RPMs
OS: Linux
Status: UNCONFIRMED
Severity: crash
Priority: NOR
Component: UI: toplevel window
Assignee: kdevelop-bugs-n...@kde.org
Reporter: nos...@tils.org
If I start kdevelop on my external screen (with 120x120dpi) it starts normal
and I can work with it. If I try to start it on my internal laptop monitor
(with 192x193dpi) it hangs and uses one cpu at 100%.
As a test I started kdevelop with Xephyr using different dpi values:
Doesnt work:
Xephyr :1 -ac -dpi 192 -screen 1480x1680 &; DISPLAY=:1 kdevelop
Does work:
Xephyr :1 -ac -dpi 96 -screen 1480x1680 &; DISPLAY=:1 kdevelop
I tried a few resolutions, it seems that the highest working value is 164 DPI.
Any start of kdevelop with a setting above 164 DPI will cause kdevelop to hang
at start. When I test it here in Xephyr I can see it instantly. If it hangs, I
can not select any Text in its Editor or klick somewhere.
Reproducible: Always
Steps to Reproduce:
1. Xephyr :1 -ac -dpi 192 -screen 1480x1680 &
2. DISPLAY=:1 kdevelop
Actual Results:
Kdevelop hangs and cant receive input
Expected Results:
It does not hang
