 Posted: Fri Jul 25, 2025 9:31 pm Post subject: Bug report: top half of CE window gets corrupted |
 |
|
hi,
I've noticed for some time, the top half of the primary CE window becoming corrupted visually. Temporary workaround is to resize window to minumum vertically and then back up to whatever height, no need to actually let go of LMB during this just at end works okay. The actual visual data that appears, seems similar to what is currently displaying in bottom pane of main CE window. It's only very recently that I've noticed that this happens after:
1. Hibernate my Windows 11 system.
2. Power off
3. Power on (after power off for some reasonable number of seconds)
4. Start up from hibernation to continue session.
My guess is that there are certain hoops to jump through following a hibernation event, and that CE is not taking all appropriate actions in this regard.
It could be that opening additional windows exacerbates the issue. It appears that the only way to stop the corruption is to restart windows (and thus lose your session, so not suitable in middle of a game, thus the workaround being essential to know while this issue exists).
My system was new in late 2023, AMD CPU, nVidia GPU, 32GB memory. 2x SSD, 4x HDD. Using 4K desktop/monitor with 1/2 scaling.

instead of hibernate, try normal sleep.
besides that no idea. Try other lazarus applications and see if they have the same issue, and try turning of dark mode support in CE in case you're using it

Thanks! I'm actually trying out your previous suggestion, managed to do the settings as you suggested. Fingers crossed! Sleep not viable alternative for me ongoing due to power savings with power completely off.

Here is something else to try as well.
Right click your shortcut and then compatability tab.
Click button to Change high DPI settings
Then check the box for Override high DPI scaling behavior
Can even try doing this:
| Code: | -- Cheat Engine: Visual Redraw Hotkey Script
-- Binds F12 to force CE main window repaint (fixes corruption after hibernation)
-- Destroy old hotkey if reloading script
if redrawHotkey then
redrawHotkey.destroy()
redrawHotkey = nil
end
-- Function to force redraw of the main form
local function forceRedraw()
local form = getMainForm()
if form then
form.Invalidate()
form.Repaint()
print("[CE Redraw] Main window repaint triggered.")
else
print("[CE Redraw] Failed: Main form not found.")
end
end
-- Bind the function to F12 (you can change VK_F12 to another key)
redrawHotkey = createHotkey(forceRedraw, VK_F12)
-- Notify user
print("[CE Redraw] Hotkey set: Press F12 to refresh CE window.")

After some hours and twice hibernating (with power off) the corruption is back. Probably your refresh hotkey idea is decent workaround, thanks.

| Did you try the settings on the properties of a shortcut to CE?

Yes, did that followed by using CE in usual way, including hibernating with power off twice. Sometime after the second hibernation I noticed some corrupting coming in again. I don't have anything definitive proving that hibernation has anything to do with issue, it's more that it's my most recent attempt at finding something that triggers it. I remember having issues that definitely seemed to be from hibernating, when using older CE version. I'm using 7.6 now. Even the game I'm playing has issues with hibernation combined with power off. For example, in game sounds can start echoing (repeating) badly when timescale is reduced, yet after a restart and before any hibernation event, the issue never occurs. As ex software engineer, makes me think that some apps must be doing quasi-legal things that don't get picked up until there's a hibernation event. I used to in my debugging days, make tools that would entice target apps to fail unless code was virtually bug-free. Watching for read or write memory after free, that sort of thing. Because powering off after a hibernation event effectively corrupts or randomises memory that isn't specifically allocated, I imagine that on this platform it would be similar to the use memory after free? In any case I see issues arise if power off happens subsequent to hibernation that otherwise doesn't arise for hibernate only.

Is "Invalidate" defined for the form?
Maybe write a definition for it.
| Code: | if redrawHotkey then
redrawHotkey.destroy()
redrawHotkey = nil
end
-- Trigger the form's layout engine with both a horizontal and vertical "jitter"!
Invalidate = function(s)
s.Width = s.Width + 10
s.Height = s.Height + 10
s.Width = s.Width - 10
s.Height = s.Height - 10
return s
end
-- Function to force redraw of the main form
local function forceRedraw()
local form = getMainForm()
if form then
Invalidate(form)
form.Repaint()
print("[CE Redraw] Main window repaint triggered.")
else
print("[CE Redraw] Failed: Main form not found.")
end
end
-- Bind the function to F12 (you can change VK_F12 to another key)
redrawHotkey = createHotkey(forceRedraw, VK_F12) |

so far, I've been using the forced redraw by clicking on corner of window (corruption happens not just to main window but others also, eg if I open script for editing), moving mouse so window is minimum height (or near to it) and then up to near whatever size it was. While this workaround is working I'm hesitant to add script to do same although may have a go a bit later. Thinking of how I could do it without using hotkey actually.

If you package this code with a timer as .lua and place it in the autorun folder, the code can detect any discrepancies between the timer and the system time and perform a refresh.
| Code: | local function refreshVisibleForms()
for i = 0, getFormCount() - 1 do
local f = getForm(i)
if f.Visible == true then
f.Width = f.Width + 5
f.Height = f.Height + 5
f.Width = f.Width - 5
f.Height = f.Height - 5
f.repaint()
--print("✅ Refreshed:", f.Name)
end
end
end
local lastTime = os.time()
if lstmr2 then lstmr2.Destroy() lstmr2=nil end
lstmr2 = createTimer(MainForm)
lstmr2.Interval = 1000
lstmr2.OnTimer=function()
local now = os.time()
--print(now)
if now - lastTime > 5 then
refreshVisibleForms()
print(now - lastTime)
end
lastTime = now
collectgarbage()
end
lstmr2.Enabled = true |
Sleep mode stops the timer, provides a time offset, and upon waking from sleep mode, the timer calculates the time offset and initiates the necessary action.
The problem is that a timer stopped by sleep mode does not restart upon waking from sleep mode.
Therefore, it cannot perform the necessary calculations and interaction.
---------------------------------------------
For this reason, the most effective solution for now is a shortcut key combination.
If you package the code below into a Lua file and place it in the CE autorun folder, you can refresh CE and other open forms with the F12 key (or F4 or F each time the system wakes up.
| Code: | local function refreshVisibleForms()
for i = 0, getFormCount() - 1 do
local f = getForm(i)
if f.Visible == true then
f.Width = f.Width + 5
f.Height = f.Height + 5
f.Width = f.Width - 5
f.Height = f.Height - 5
f.repaint()
--print("✅ Refreshed:", f.Name)
end
end
end
if lstky2 then lstky2.Destroy() lstky2=nil end
lstky2 = createHotkey(refreshVisibleForms, VK_F12) |
----------------------------------------------
So, did you use "Refresh" from the desktop right-click menu after waking from sleep mode?
What are the results if you apply it?
I hope this isn't a system issue.
Otherwise, system repairs like "restoreHealth" may be necessary.
