Comment 3 Nate Graham 2023-02-22 17:55:39 UTC 
Reproduction steps from other bug report:
1. Press Klipper hotkey to show history  at mouse position
2. Switch to cyrillic
3. Type something to filter records 
4. crash/freeze.
Comment 4 Nate Graham 2023-02-22 17:56:31 UTC 
Just tried that and it didn't happen to me.

The backtrace indicates that it's deep in graphics code. What kind of GPU do you have? And have you forced Plasma or KWin to use a non-default rendering mode?

Tried OpenGl or Automatic - what else?

All right, NVIDIA GPU with the proprietary drivers, thanks.

Crashes also with Latin keyboard, also when browsing in chrome based browser, etc.

Of course it also crashes very often accidentally without any reason as well. Please fix. Same crashes are in 5.27.1 version.
Comment 9 Fabian Vogt 2023-03-03 07:28:23 UTC 
Apparently you use the QML software renderer. That should not be the case, did you configure that explicitly in kcmshell kcm_qtquicksettings?

No, after the crash "kcmshell5 kcm_qtquicksettings" appeared for me so I tried any variants: Program, OpenGL, Automatic - all crashes.

Please switch to OpenGL, when it crashes again attach a backtrace.

Already switched, but problem is crash sender UI never appears, while it crashes or freezes all the time.

If it's frozen (or crashed but somehow hangs instead of restarting), you can run

gdb -ex "thread apply all bt" -ex "kill" -ex "q" -p $(pidof plasmashell)

That was tricky: Klipper filtering freezes plasma hardly - several CPU completely loaded, no keyboard response, so forced to do this in virtual terminal switching by Ctrl-Alt-F1 and redirect output to a file - see attachment below.

Right after the 1st crash (freeze), 2nd one happened accidentally (did nothing at that time: browsing in chrome based browser). See Attachment #157160 [details].

3rd crash just happened then auto-restarted - so was unable to catch the stack trace.
Comment 19 Fabian Vogt 2023-03-10 07:26:46 UTC 
I see that plasmashell still uses the software renderer, so the switch to OpenGL did not work.

However, it looks like in both backtraces it's busy in clipboard history code. In plasma_error_2.txt, it's saving a copied image to disk.

Another bug?

What was changed in 5.27 that causes it?!
Comment 21 Fushan Wen 2023-03-10 11:29:30 UTC 
If you clear the clipboard history, will the bug still exist?

> If you clear the clipboard history, will the bug still exist?

Cleared, copied some. With 1 record - no. Will check further when have more records. Why does not switch to OpenGL, how to switch?

klipper: remove duplicate items when loading from history

Due to a catastrophic bug existing in 5.27 beta and 5.27.0, there could
be duplicate items in klipper's history file, so filter them out here.

The popup menu will try to read `item->next_uuid()` in a loop to fill the menu, hence it's possible to create an infinite loop when there are duplicate items.
