Bug ID: 466211
Summary: file previews of images in file-open dialog consumes a
lot of cpu and causes errors in updating the dialog
(elements are overdrawn)
Classification: Plasma
Product: xdg-desktop-portal-kde
Version: 5.27.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: slartibar...@gmail.com
CC: aleix...@kde.org, jgrul...@redhat.com, n...@kde.org
Target Milestone: ---
In wayland using chrome or firefox, the xdg file open dialog and save-as (using
xdg-portal) is broken when operated by keyboard
Setup:
Use the env.Var GTK_USE_PORTAL=1 and start firefox or chromium-freeworld, then
try to open a file with Ctrl-O.
The open-file Portal dialog comes up.
Problem:
- select a folder containing lots of images (where no previews were rendered
before)
- you notice kioslave consuming a lot of cpu in the background
- (prepare beforehand: have two 7z zipfiles inside the image folder containing
(other) images, both ~250MB in size)
- click on those .7z files (or select them with the keyboard)
- now, use either the mouse or keyboard and try to navigate away from the
selected 7z file
- the dialog does still refreshes the preview panel, but the file selection
inside the list-panel is broken
(elements overdrawn, multiple selections, lots of bad stuff)
- the name field still follows you selection (as does the preview) so the
dialog still somehow works until you try to go to the parent directory with
Alt-cursor-up.
- Then, the dialog is completely broken and unusable
