I write a RCP program with eclipse3.8 a long time ago, recently, I upgraded it to eclipse4.13. Then, I find, When I use input Chinese characters, it always crashes. But when I use the English input method, it works well. -- Configuration Details -- Product: Eclipse IDE 4.13.0.20190917-0000 (org.eclipse.epp.package.rcp.product)Installed Features: org.eclipse.platform 4.13.0.v20190916-1323
Created attachment 280890 [details] The crash logs The crash logs
I found a little clue: maybe is the autoScaleDown method in the org.eclipse.swt.internal.DPIUtil.java caused the crash. When I use the following methods: gc.drawImage(icon, x, y) gc.getFontMetrics().getAverageCharacterWidth() it call autoScaleDown,then crash. I used a 4k HiDPI screen(3840*2160), and with scale 250%, windows10 system. also, maybe org.eclipse.swt.graphics.GC.drawTextInPixels caused crash?
I also call gc.setLineWidth() method, and use Chinese input method when the control loses focus，it crash！
(In reply to gong md from comment #3) > when the control loses focus，it crash！ Do all your experiments some steps involving focus? Could you try with a more recent version, e.g. 4.14M3? This might be bug 551067 which is fixed since 4.14M1.
Yes, sounds like a duplicate of bug 551067. Please reopen if the crash still occurs with 4.14 M1 or higher version. *** This bug has been marked as a duplicate of bug 551067 ***
I will test it on version 4.14RC2
I tested on version 4.14RC2, still crash...
In version 4.13, when the control loses focus,only use chinese input method can cause crash, use english input method not crash。 but in version4.14RC2, when the control loses focus, the frequency of crashes has been reduced so much that I once thought that the bug was resolved。But occasionally it still crashes, whether using Chinese input method or English input method。
