Not sure how to reproduce this one, I just know that it only happens on wayland.
After a period of development if you start typing theIDE will just freeze. You kill it, reopen it and try typing again, it will freeze again. A gdb external session indicates it's stuck in an infinite loop waiting for input from the clipboard. I've tried clearing the global clipboard and it still freezes. When I switch to X11 the problem goes away. I'll try to get a backtrace on it next time it happens.
EDIT Just remembered something: I have been able to get it to break out of the loop by copying something into the clipboard from another app.

Hello,
Since last week I have the exact same problem (never had this one in all the years using Ide before) : Ide freezes when I type a letter (It comes back to life after some time I didn't measure the time but about 20s or more ==> the poll timeout ?)
It all started when I created a new sub package for my app and directly decided to erase it (using delete form Ide menu).
Since it started on an action I rarely do: I thought some congif or tmp files were messes up, so I tried erasing all the working data in the directories but Ide would still always freeze once I type the first letter.
To make it work again I had to rename my Ide to something else in order to provoque a fresh install (and therefor new .cache and working directories).
Since this morning, Here it is again 
I compiled theide in debug mode (I have the lattest git version no more than a few days old) and launched in debug ==> same freeze happens !
I erased the clipboard ==> still getting freeze
Here is the backtrace I get:
Thread 1 "ide" received signal SIGINT, Interrupt.

Note the key pressed should be a 'v' or 'tab' (I may be mistaken)
I tried to get other backtraces in other conditions : I always get the same backtrace result
It seems quite strange : I type a letter, it freezes, and the backtrace points at Upp::Bar::Scan() which, at the end waits for clipboard entry ???
My exact Git version is:

Here is the code for Upp::LineEdit:1258
bool LineEdit::Key(dword key, int count) {
NextUndo();
switch(key) {
case K_CTRL_UP:
ScrollUp();
return true;
case K_CTRL_DOWN:
ScrollDown();
return true;
case K_INSERT:
OverWriteMode(!IsOverWriteMode());
break;
}
bool sel = key & K_SHIFT;
dorectsel = key & K_ALT;
dword k = key & ~K_SHIFT;
if((key & (K_SHIFT|K_ALT)) == (K_SHIFT|K_ALT))
k &= ~K_ALT;
switch(k) {
case K_CTRL_LEFT:
{
PlaceCaret(GetPrevWord(cursor), sel);
break;
}
case K_CTRL_RIGHT:
{
PlaceCaret(GetNextWord(cursor), sel);
break;
}
case K_LEFT:
MoveLeft(sel);
break;
case K_RIGHT:
MoveRight(sel);
break;
case K_HOME:
MoveHome(sel);
break;
case K_END:
MoveEnd(sel);
break;
case K_UP:
MoveUp(sel);
break;
case K_DOWN:
MoveDown(sel);
break;
case K_PAGEUP:
MovePageUp(sel);
break;
case K_PAGEDOWN:
MovePageDown(sel);
break;
case K_CTRL_PAGEUP:
case K_CTRL_HOME:
MoveTextBegin(sel);
break;
case K_CTRL_PAGEDOWN:
case K_CTRL_END:
MoveTextEnd(sel);
break;
case K_CTRL_C:
case K_CTRL_INSERT:
Copy();
break;
case K_CTRL_A:
SelectAll();
break;
default:
dorectsel = false;
if(IsReadOnly())
return MenuBar::Scan(WhenBar, key);
switch(key) {
case K_DELETE:
DeleteChar();
break;
case K_BACKSPACE:
case K_SHIFT|K_BACKSPACE:
Backspace();
break;
case K_SHIFT_TAB:
AlignChar();
break;
case K_CTRL_Y:
case K_CTRL_L:
if(cutline) {
CutLine();
break;
}
default:
if(InsertChar(key, count, true))
return true;
return MenuBar::Scan(WhenBar, key); ******************* L1258 *******************
}
return true;
}
dorectsel = false;
Sync();
return true;
}
I guess InsertChar() didn't work for some reason ?
Note : all is running again ... and I didn't do anything to correct it (Assist is still running)

Hello Dider,
Thanks for report! Can you provide more information about your setup? I mean OS, U++ version. Desktop Environment, GTK version, Wayland or X11 etc.?
Edit: I found the version number in your message (b99c26b267b2a484ee709024ae0e1e0a1e5e1258). So, this information is no longer needed 
Klugier
U++ - one framework to rule them all.

Didier,
Yes, I think you found it. That looks like the same backtrace I had in gdb. It's entirely possible I mistakenly thought clearing the clipboard externally fixed it when it was simply the timeout being reached at coincidentally the same time, although IIRC I have triggered it also during a copy+paste operation. When I tried to paste the contents externally to see what was in there the buffer appeared to be empty. Maybe it had something bad in there?
But mainly what I don't understand is why you could be trying to just type things normally, no special characters or commands and it's checking the clipboard. Is TheIDE doing this after every key event? There may be a good reason for this, but I can't think of one.

I'm gonna lookup the 'key' value : since 'InsertChar(key, count, true)' doesn't react as expected, I suppose it's due to the valey of 'key'.
Context: I was trying to type " virtual void Skin(..."
'v' ==> 0x76
'V' ==> 0x56
'tab' ==> 0x09
The 'key' values cought from the backtrace:
67108873 => 0x0400 0009 looks like 'tab'
69206102 => 0x0420 0056 looks like 'V'
So I guess the problem will comme from the 0x0400 0000
The only thing that I can find that is close to it is:
CtrlCoreFlags::K_KEYUP = 0x4000000
Looking at 'InsertChar(...)' the constants used have the following value on may Linux.
K_CHAR_LIM = 0x0200 000
K_ENTER = 0x0d
K_SHIFT_SPACE = 0x0080 0020
So with the 'key' values from backtrace
0xXXX 1 true
bool LineEdit::InsertChar(dword key, int count, bool canow) {
if(key == K_TAB && !processtab) **** TEST IS FALSE ****
return false;
if(filter && key >= 32 && key < K_CHAR_LIM) **** TEST IS FALSE ****
key = (*filter)(key);
if(!IsReadOnly() && (key >= 32 && key < K_CHAR_LIM || key == '\t' || key == '\n' ||
key == K_ENTER && processenter || key == K_SHIFT_SPACE)) **** TEST IS FALSE ****
{
if(key >= 128 && key < K_CHAR_LIM && (charset != CHARSET_UTF8 && charset != CHARSET_UTF8_BOM)
&& FromUnicode((wchar)key, charset) == DEFAULTCHAR)
return true;
if(!RemoveSelection() && overwrite && key != '\n' && key != K_ENTER && canow) {
int64 q = cursor;
int i = GetLinePos64(q);
if(q + count - 1 < GetLineLength(i))
Remove((int)cursor, (int)count);
}
WString text(key == K_ENTER ? '\n' : key == K_SHIFT_SPACE ? ' ' : key, count);
Insert((int)cursor, text, true);
PlaceCaret(cursor + count);
Action();
return true;
}
return false; **** Exit comes from here ****
}
The origin of the problem is definitly the 0x4000000 bit set in the value
Looking at the void Ctrl::Proc() in GtkEvent.cpp ==> CtrlCoreFlags::K_KEYUP is definitly used
I thoink the 0x0400 0000 value comes from the line :
DispatchKey(!pressed * K_KEYUP + kv, CurrentEvent.count);
==> Keyboard is malfunctionning : key returns up before being completly processed ??
Note: I do have a brand new Dell wireless keyboard ==> Is this it : a keyboard problem (or kbd driver problem)????
